590 5/23/2002 9:33:06 PM 5/24/2002 John Clark jvclark02@cs.com 84 SLIDE OUT?????????? I saw your original post on the bus conversions BB. I doubt if Newell can/will answer your question due to liability issues. If they say yes and you hire an inept installer and the chassis fails you could come back at them based on their ok. I suggest you visit their factory and see how a Newell is built. It is truly unbeliveable how much steel goes into a Newell frame. I do know they are putting up to four slides into their latest models, but you will have to decide for yourself if the retrofit of a slide out is adviseable. In my humble opinion, if I were going to add a slide out to a motorcoach (I'm not), I would choose a Newell over anything else.

installed in our new 1989. I did not trust DDEC. It ran perfect, In our new 1992 coach we had DDEC. (NO CHOICE),
We went through 4 moduals till we got one that would last
more than 25,000 miles. Horible times when they go into thier fits.

Q
601 6/1/2002 10:30:28 AM 6/3/2002 Art Knapp agkcpa1@hotmail.com battery charger Regarding the merge switch on the dash - does it make any difference whether the switch is merged in the up or down position?
Also, if you wire a new inverter (Heart 458 series) with 3-stage battery charging to the merge solenoid, will the 3-stage charging be effective on both battery banks when in the merge position?
If not, how and where would you connect the battery banks with a battery combiner (such as Pathmaker) or a Heart Digital echo-charge? The objective would be to use 3-stage charging on both banks, but still keep them isolated unless needed for emergency starting.

602 6/1/2002 11:13:02 AM 6/3/2002 Art Knapp agkcpa1@hotmail.com Shunt to measure house current I am having a Heart Inverter installed in my 1983 Newell. I would like to add the Link 1000 or 2000 Battery Bank Monitor. The Monitor uses a 500 amp shunt to measure the current. The instructions for the Monitor indicate that the Negative cable from the House 12-volt system distribution system needs to be attached to one post on the shunt and the Negative battery cable needs to be attached to the other post on the shunt. My house 12-volt distribution system in in the hall closet. There does not appear to be a negative or ground terminal for this panel. There appears to be an existing shunt already installed on the Positive side of 12-volt panel. Perhaps this shunt measures the current as displayed on the analog meter that is located on the cabinet door above the driver seat. Do ytou have any comments or suggestions?

606 6/2/2002 4:37:50 PM 6/3/2002 Don Koenig donkoenig@juno.com Generator Failure one phase only With the generator running one phase voltage meter read 30-40 volts while the other showed 120 volts. I think the failed phase was getting feedback voltage from the 240 volt fan motor. I found a burnt through wire in the controller box at the generator circuit breaker. Has anyone else had such a problem? The Hobbs meter shows 2967 hours on the generator. The coach odometer shows 212,783 miles. Could fatigue have weakened the stranded copper wire? I feel lucky it did not touch another terminal on the circuit breaker or the metal of the controller box. I am sending a letter to Kohler. Maybe I will get something from them. Don

607 6/2/2002 5:52:27 PM 6/3/2002 Rich Farr toptin@aol.com 79 Newell solenoid panel Our 79 Newell has 4 solenoids (mounted in square pattern)inside right rear tail light door (next to radiator). Facing front of coach;
LH bottom = battery merge;
RH bottom = engine start;
RH top = engine stop;
LH top = unknown;
The labels have long since vanished and thusfar, am unable to identify what LH top is used for - could anyone please share that info?
The driver for sudden interest in these solenoids is, that the battery merge solenoid has gone bad (shorted).
When I went to the local solenoid store, it was amazing how many different solenoids there are on the market.
In the absence of part number/s it seemed reasonable to replace with high amp (80), normally open, rated for continuous use. It stopped the short, but fails to energize - so still no battery merge.
Would love to have a solenoid brand name, part numbers and tech specs info for those 4 solenoids.
Thanks in advance for assistance..
Best,
Rich farr

600 6/1/2002 10:15:13 AM 6/3/2002 Art Knapp agkcpa1@hotmail.com Removal of old inverter I have a 1983 Newell.
I removed the original Honeywell 1500 Watt Power Generator (inverter). I am having a Heart Inverter Installed (Series 458, 3000 watt, 12-volt).
In the compartment where the old inverter was is a plug (male) labeled "Inverter". Several 120-volt outlets in the coach ran from this single plug when the inverter was working.
There is also an "Inverter" On/Off switch located on the dash panel.
The new inverter will be professionally installed using a new 30-amp sub-panel located at the 120-volt main. It will run from one leg of the 2-leg 50-amp main.
Do I need to remove or re-route any of the 120-volt wiring associated with the old inverter?
Thanks for you help.

We recommend that the Jacobs engine brake be serviced by an authorized service service shop for the particular engine brand your friend has. Jake brakes occasionally require a simple adjustment, or a wire on the switching system may have come loose.

614 6/8/2002 7:22:49 AM 6/9/2002 Tech Talk Staff TechTalk@newellcoach.com 79 Newell solenoid panel The correct solonoid can be confirmed, and a new solonoid ordered, by calling the Newell Service Department at 1-888-3NEWELL (1-888-363-9355). Yes, we also recommend the somewhat more expensive but much more reliable continuous duty solonoids, particularly for the battery merge circuit. Keep in mind that the battery merge switch on the dash is wired for "off" in the center, and powers up using one bank of batteries in the up position, and the alternate bank of batteries in the down position.

616 6/8/2002 7:38:31 AM 6/9/2002 Tech Talk Staff TechTalk@newellcoach.com solar power We suspect you are referring to the Kool-O-Matic attic fans on the roof. Anyone qualified to install solar power panels should be able to measure the amp draw when the fans are operating and size the solar system appropriately for this and whatever other loads you intend to run. Although solar power is an interesting, attractive concept, our experience is that is relatively expensive for the limited amount of current that it will generate, and therefore has not proven to be very popular. It has generally been installed on Newells to keep batteries properly charged in long-term outdoor storage lacking electrical hook-ups. Solar is a rather elegant solution to this situation.

617 6/8/2002 7:43:07 AM 6/9/2002 Tech Talk Staff TechTalk@newellcoach.com Shunt to measure house current The shunt for a Link battery monitor should be installed on the negative cable of the appropriate battery bank to be measured, not at the interior distribution panel. If the engine battery bank is to be measured, insure that any grounding straps on the engine at installed so as the connection to ground from this strap travels through the shunt before finding ground.

618 6/8/2002 7:50:36 AM 6/9/2002 Tech Talk Staff TechTalk@newellcoach.com Removal of old inverter As your message implies, the installation of a new, different inverter system is a somewhat complex project and is best handled be an experienced professional, as you suggest. The specifics need to be sorted out by the installer, particularly as many coaches have been modified through the years from their original confirgurations. The male plug you mention sound like it might lead to inverter powered components, and this should be confirmed by actual testing. The factory has often used a male plug to connect inverter loads to the inverter so that these loads can easily be connected directly to the 120 volt system, by-passing the inverter, should the inverter fail.

611 6/7/2002 8:09:31 PM 6/8/2002 B. Johnston NMBJohnston@aol.com 79 Newell solenoid panel I just recently purchased a 35' model from the same year. I looked and found the labels you have mentioned in your e-mail. The one in that position says "cruise control". Unfortunately, I can't find a brand name or part numbers on the solenoids anywhere. I don't know much about motor home electronics so I'm afraid I can't give any more help at this time. My cruise control is not working; I may know more about this solenoid when I have it looked at later this summer.

612 6/8/2002 7:10:17 AM 6/9/2002 Tech Talk Staff TechTalk@newellcoach.com Overheating Yes, we have heard that installing a system to "mist" the radiator (perhaps at the push of a button) provides additional cooling for an intermittent overheating situation. We have had no direct experience. Further, the cooling system should be able to properly cool the engine and transmission (a trans temp of 200 is not normally a problem) without any add-on devices. But proper maintenance of the cooling system, particularly the radiator itself, is critical. We recommend that you first confirm that your radiator is clean. If there is a buildup of oily fluids and road film, the radiator should be carefully washed from the outside to the inside to knock off the crud, best accomplished with a car wash low pressure wand. It is also possible that road blast over the years has gradually knocked off the fins on the radiator tubes. This requires the radiator to be rebuilt or replaced.

626 6/12/2002 9:02:04 AM 6/12/2002 John Clark jvclark02@cs.com Overheating A lot of car washes won't allow radiator cleaning (they think you are washing the engine) so I carry a small garden sprayer to presoak the radiator with hot soapy water or mineral spirits and than flush with a garden hose. To cure the road blast problem (bent fins) I installed hardware cloth under the engine to keep small stones from coming up trough the fan. This is a must modification if you plan on visiting Alaska. For me a 200 degree transmission temperature is fine and IAW Allison and Detroit Diesel reps. guidance. I have used the cooling system you mentioned, but I have not installed it on my '87. They were developed by bus companys who had to climb the Baker grade to Las Vegas in the summer. You can purchase the unit through ads in Bus Conversions Magazine or make one your self using a Rain Bird sprinkler solenoid (12 volts will operate the 24v solenoid) and some hardware store mister's.

627 6/12/2002 9:18:20 AM 6/12/2002 John Clark jvclark02@cs.com jake brake I have had to repair my Jake three times and in each case the problem was electrical rather than mechanical. Have someone activate the switch (key on, engine off) while you put your ear close to the valve covers (no background noise) If you here the slight click of a solenoid activating inside the valve cover (you may need your wife to do this if your hearing is bad like mine) than you need to take it to a shop because the solenoids are working. If no click, start trouble shooting the 12V wire that comes from the dash to the engine. In one case it was broken where it entered the valve cover, in another it was the switch that was located on the transmission, and in the third it was the idle switch on the throttle linkage, (which must be activated before the jake will work).

628 6/12/2002 10:05:17 AM 6/12/2002 John Clark jvclark02@cs.com solar power I use a solar/inverter system on my '87 Newell and like Newell's reply, it is expensive. I suggest that rather than a solar generator on the top of your two fans, you install a full size panel (+-100 watts)with a controller to charge your batteries. That way when the sun is at its highest you are gaining amps, to make up for what was lost in the late afternoon or evening. In my case I have four panels with a 20 amp total charging capacity at high noon and a large battery bank that significanly reduces my genset requirements while in "quiet" areas. A lot of people don't realize that if you use a propane refrigerator you are consuming amps to keep the 12v solenoid open, which along with other phantom amperage users will drain your batteries over time. If you are "dry" camping be sure to check that your merge and air solenoids are actually off (not warm to the touch), as they will do a job on your battery along with the propane shutoff solenoid found on some units and the humidity controller on Dometic refrigerators.

630 6/13/2002 4:15:03 AM 6/18/2002 John Clark jvclark02@cs.com noisy transformer I had the same problem on my 79 and my 87. The converter on my Newells were a large siver box about the size of two toasters placed end to end and made a humming noise 24/7. These things are 'old' technology and tend to be hard on battery banks because of their taper type charging. I suggest replacing it with a three stage charger/inverter (bulk, acceptance, float). There are a number of brands and units available to match your budget, most of which are owned by Xantrex of Vancouver BC. (Trace, Heart, Statpower etc.). If you are willing to spend the bucks, I think the pure sinewave statpower inverter/charger is the best, but I have had good luck with Heart and Trace also. Go to www.xantrex.com for more info.

635 6/17/2002 6:27:39 PM 6/18/2002 Bob Marlatt InsideGolf@cablespeed.com 1972 Newell Motor Coac h Leon, the Jake Brake you refer to is actually a transmission retarder. It is essentially a series of fins that spread out in the transmission and works against the transmission fluid. On your dash is heat-gauge for your transmission which is quite important when using the retarder because of the heat build-up from the friction between the fluid and the retarder fins.
Your's may actually work. The next time you're coasting down a hill, press the peddle and hold it for a while, it's slow in taking ffect, and see if it has an effect. I also have a '72 and have found this device to be quite a blessing coming off mountain passes.

640 6/19/2002 8:37:42 PM 6/20/2002 Bob Scott thescotts@proaxis.com Overheating We have an 86 coach and it would heat up on a long hard pull. It had a spray system installed by the previous owner. In looking the cooling system over it was obvious the radiator was bad. I took the radiator to several repair shops for their recommendations. The route that I went was to add another row of cooling tubes (the top and bottom tanks are large enough to accomodate this increase) and went to a tube that has rippled walls. This feature slows the flow of water through the radiator and allows the air a better chance to cool. I also rebuilt the spray system as the old one did not disperse water over the radiator at higher engine RPMs. We have about 20,000 miles on this rebuilt radiator in all kinds of weather and mountains and as yet have not hooked up the spray. I have to run real hard to get the temp up over the 180 mark. Also keeping it clean cannot be over stressed. I hose it down after each major trip. Good luck.

The correct model KIP valve will replace the original Skinner valve. Also, the rebuild kit is a good choice if you do the work yourself. However, if you have to pay shop labor, here or elsewhere, to do the rebuilding, the economics of the rebuild option go away.

Our engine temp will get to 210 on grades, and it makes me quite nervous. I've had trouble getting a consistant answer as to what is too high, and have heard from other owners who experience same temps. Some at Newell have stated that such a temperature is within reason. I've even gotten differing words from Detroit service centers. I too would like more definitive word on where the red line is.

644 6/24/2002 4:53:23 AM 6/24/2002 Tech Talk Staff TechTalk@newellcoach.com Overheating A Detroit 92 Series engine will run at 210 degrees without a problem. However, that doesn't leave much "headroom" for additional heat such as might be generated on a long, steep hill in the summer. An engine running at 210 is okay, but let it run up to 215 and start to look for either an automatic shutdown or, if the shutdown system doesn't activate, trouble.

645 6/24/2002 1:05:12 PM 6/25/2002 John Clark jvclark02@cs.com 1980 Newell Coach I have had the best results with Delo 100 40wt. Shell Rotella 40wt., and Delo 400 40wt., have done fine, but the Delo 100 seems to have provided the best pressure and oil consumption numbers. If you go to the Detroit Diesel lubricant web pages, you will find all three oils are acceptable with the Delo 100 coming closest to their low sulphur requirements I have an oil analysis done with each oil change and I can't tell a difference (trend) in the numbers. I have nothing against synthetic oils except the price and I use them in my transmission where the price per mile traveled seems more realistic. Newell has been using synthetic oil for years and I highly endorse their recommendations.

646 6/25/2002 9:14:16 AM 6/25/2002 Tech Talk Staff TechTalk@newellcoach.com 1980 Newell Coach John makes a good point about synthetic lubricants. We are convinced that the Mobil synthetics are excellent products, among the finest lubricants available. But they are pricey. In a new or late model expensive coach, we think they are justified, so that's what we use for initial factory fill (when we are paying the bill) and in the factory service department unless a customer specifies differently. However, it may not make economic sense to use some of these products in older coaches. We also agree with John that the transmission fluid falls in a different category. Not only can the drain intervals be extended without concern, but the synthetic fluid can sustain higher temperatures without breaking down. This might save an older transmission with a minor problem that causes an overheat from a consequential breakdown of the ATF and a total failure.

651 6/28/2002 8:39:12 AM 6/28/2002 Tech Talk Staff TechTalk@newellcoach.com 1980 Newell Coach It is correct that, as a general rule, multi-grade oils should not be used in Detroit Diesel Series 92 engines. However, Delvac 1 synthetic is an exception. We have used multi-grade Delvac 1 backed up by oil analysis for twelve years. It is an excellent oil for a 92 Series engine. However, the anti-multi-grade culture at Detroit is strong, and the "Newell/Mobil" exception to the general rule is not well known in the trenches. Detroit now offers a straight weight version of synthetic engine lube, a choice that many of the old-time service people are more comfortable with.

The check engine light and the shutdown are more accurate than the temperature gauge. If the gauge shows a high reading but no check engine light comes on, keep on truckin'.

In the mid to late 80's, Detroit Diesel came out with DDEC (Detroit Diesel Electronic Control) that allowed an increase to 500HP and still meet EPA emission requirements. Newell Coach was the first (or close to it) to meet the cooling requirements of Detroit and install the engine in a motor coach. It is relatively simple to boost an 8V92TA Detroit Diesel to 525HP (goodbye warranty and emission compliance) and that may be what you have seen. Two cycle Diesel engines are fantastic for power to weight ratio's, but notorious for high exhaust emissions and thus have been relegated to marine and industrial use only.

I took the '79 to the factory for alignment and they said everything was right on specs. I don't know the cause or solution, but I was able to significantly reduce it by switching to steer tires. I use Toyo steer tires, because they have a reinforced outer ring to reduce cupping. I tried to find Goodyear G78's steer tires, but they are a universal position tire and lack the reinforced ridge. I buy two front tires every few years and than move them to the rear as the outer edge begins to wear. I swear they ride better than drive tires, but can't prove it. I have close to 200,000 miles on my Newells, and have experienced only one flat (I discovered it in a rest area just before a 3 mile bridge). I carry a handheld non-contact thermometer to quick check my tires, among other things.

Q
700 7/26/2002 4:43:54 AM 7/26/2002 Tech Talk Staff TechTalk@newellcoach.com Transmissions 4,5,6 speeds? Transmissions allow the vehicle operator to run the vehicle engine either at higher rpm, for more power and acceleration, or at lower rpm, for better fuel economy but at less power. A transmission must have enough ratios so that it can match the desired range of engine rpm to road speed from initial acceleration from a stop to top speed. With more gear ratios, a transmission can keep engine rpm within a narrower band to a higher top road speed. With fewer (and therefore wider split) ratios to the same top speed, the change in engine speed between shifts becomes greater. However, an engine with a wider, flatter power curve from low rpm to high, doesn't require as many gears as closely spaced as an engine with a steeper power curve that needs to operate at a higher rpm to develop the desired torque. In addition, a transmission with few, more widely split gears does not have to shift as often, so the passengers perceive a smoother flow of power. When Newell produced coaches with Detroit Diesel 6V92 engines, they used an Allison 600 series 5-speed transmission. When Newell upgraded in 1984 to the 8V92 engine with more power, they determined that the heavier duty Allison 700 series 5-speed transmission required by the more powerful engine had relatively rough shifting characteristics. Therefore, they chose the smoother shifting Allison 700 series 4-speed transmission. The logic was that the additional low rpm torque from the 8V92 would allow for somewhat wider gear splits, the transmission would shift fewer times over the same duty cycle without an unacceptable loss of performance, and the passengers would experience smoother operation. The situation changed again in the mid-1990s with the introduction of the new Allison World Transmission. The shifting characteristics of this transmission are exceptionally smooth, with shifts almost imperceptible at times. Therefore, the transmission, which incorporates 6 speeds, allows the engine to operate with a narrow, more optimal rpm range by shifting more often, but with no loss in smoothness.

701 7/26/2002 4:59:58 AM 7/26/2002 Tech Talk Staff TechTalk@newellcoach.com Airbags How Many is Enough? The number of air bags on a late model Newell three axle coach varies depending on whether the coach has a straight front (steer) axle or independent front suspension (IFS). Newell straight axles, including steer, drive, and tag, are designed around two air bags per side, or four per axle, so the coach is equipped with a total of 12 air bags on three axles. The IFS steer axle incorporates one air bag per side, so the coach has a total of 10 air bags. The requirements and total design of an axle's suspension is more important than the number of air bags. All things considered, Newell believes their two air bag independent front suspension is superior in ride and handling to the previous four bag straight front axle, while Newell currently prefers drive and tag axle suspensions that use four bags per axle.

703 7/28/2002 12:53:06 PM 7/28/2002 John Clark jvclark02@cs.com Airbags How Many is Enough? Another consideration is the air bag reservoir. My Newell has a 12 bag system with large heavy duty air tanks mounted between the frame. These tanks are connected directly to the air bags with large diameter airlines. When you hit a bump, the tanks absorb some of the increased air pressure from the air bags, thus smoothing the ride. I have yet to ride in a motorcoach with a smoother ride than a Newell.

I guess this might be different say for a 1987 and a 2003, but a range of speeds? With reguard to tires and air pressure. Can they cruise over 75 mph for any length of time safely? If so how fast. Again out in the west where there is little to no traffic in some places you just want to put the peddle to the metal so to speak.
Thanks, Pete

707 7/29/2002 7:49:28 AM 7/29/2002 TechTalk Staff TechTalk@newellcoach.com Maxium Speed We asked Alice, and she replied, "No comment." However, doing the math on a Series 60, governed at 2100 rpm, with a 6 speed Allison in 6th gear (overdrive) and the standard 4.30 rear axle, it works out to about 93 mph. As we recall, the 92 series engine topped out at about 85 mph (the difference in speed is not due to horsepower, but to the Allison World 6 speed transmission providing a "taller" high gear while still maintaining a good first gear ratio). The current standard equipment Michelin Pilot low profile tires are rated for a maximum speed of 75 mph @ 130 psi cold inflation. Michelin also indicates that an extra margin of safety can be achieved by inflating the tires an extra 10 psi, to 140 psi, but the ride suffers somewhat. NEVER BLEED OFF AIR PRESSURE BECAUSE OF INFLATION BUILDUP AT ROAD TEMPERATURES. A note of caution: use extra care operating the coach at interstate speeds in the heat of the summer. High speed combined with high ambiant temperatures can cause a tire to overheat, possibly resulting in rapid tread separation. Underinflation causes even more destructive heat buildup. CAUTION: When running in temperatures exceeding 90 degrees F., we suggest holding the speed to a maximum of 70 mph. A
708 7/29/2002 11:25:39 PM 7/30/2002 David Keith davessc@yahoo.com 35 foot Newell Floorplan I am thinking about having a Newell coach custom built, but am interested in just 35 or 36 footers.

Two questions: 1. Do these shorter Newells still have three axles (like the 1985 Blue Bird PT-36 that I am selling (http://home.earthlink.net/~davidkeith/pt36/350.html)?)

2. Where can I find example floorplans for such a shorter Newell?

Thanks, Dave Keith

709 7/30/2002 4:48:38 AM 7/30/2002 John Leuenberger jeleuen@attglobal.net '82 Electrical Recently acquired nice 82 coach. All 4 batteries less than 3 years old. Coach had been stored plugged in to shore power. Front battery plates were dry, took 4 gallons distilled water to fill. Nevertheless, batteries tested OK at local RV shop. Found that when plugged in to shore power, house batteries get very warm, they actually seem to be cooking. Doesn't the converter/charger taper off the charge as batteries charge up or is it not automatic? So guess if left connected to shore power, the batt water will eventually cook out. Also confused about merge switch. Info with coach says battery switch should be set to merge anytime batteries are receiving charge. Merge switch should be off when batteries not receiving charge. Is this correct? Last, is there a switch on the 82's to kill all battery drain when exit the coach? There is a covered panel over the door next to door bell. Previous non Newell coaches had this switch. If no battery kill switch, what about installing blade switch at house batteries? Thanx any info.

This is because the third axle competes for the space required for tankage (fuel, fresh, and holding) and for storage. Floorplan examples can be requested by calling the Newell sales staff at 1-888-3NEWELL.

711 7/30/2002 5:05:54 AM 7/30/2002 TechTalk Staff TechTalk@newellcoach.com '82 Electrical Regardless of the battery test, it sounds like your batteries are shot. Unless the batteries are relatively new, they should all (engine and house) be replaced at once. Batteries of different ages don't charge properly together. The battery charger/converter does taper to a trickle charge, allowing the coach to remain plugged in while stored. The merge switch allows the engine batteries to be charged from the 120 volt converter/charger, and also allows the house batteries to be charged from the alternator. Later model coaches handle this switching automatically. You will know if the merge is taking place automatically by monitoring the voltage on each battery bank. Voltage readings over about 13 volts means the batteries are receiving charging current. The reason to disconnect the merge function when not charging is to allow your engine batteries to stay up while the house batteries are being used for power and depleted. When its ready to go home depleted weak house batteries after dry camping, the engine batteries will still be fully charged and ready to start the coach. Finally, look through the underfloor compartments and you will find heavy duty disconnect switches for the engine batteries and the house batteries. Check close to the battery locations first. The switches are bright metal and a couple of inches across in size.

712 7/30/2002 6:42:45 AM 7/30/2002 David Carpus DCarpus@dcarpus.com Irregular Tire Wear - Cupping I had the same problem with the original equipped Goodyear's on my 87Õ coach. I replaced them with FirestoneÕs with a flexing edge on both sides. This eliminates the irregular tire wear. I am currently on my second set and have been very happy with their performance and mileage. I have had absolutely no irregular wear or cupping. However the FS507 in 11rx24.5 is not available in a ribbed radial, but I have been in snow and ice conditions and have had no traction problems. As an additional note, they are made on the same line as the Brigstones.

One more question about the merge switch, what's the difference between forward or rear position? Thanks again.

714 7/30/2002 3:15:28 PM 7/30/2002 TechTalk Staff TechTalk@newellcoach.com Merge Switch Reminder: you should not install new batteries on your house system without replacing the engine start batteries at the same time. The voltage regulator cannot properly adjust the current to a mixture of new and used batteries. The merge is off when the switch is centered, and the switch merges the batteries pushed in either the up or down position. One direction merges using engine batteries to power the merge solonoid, the other position merges using the house batteries. Therefore, the system can be used as an emergency merge if either battery bank is dead.
