Excuse my ignorance on the subject, but what is a "Fast Idle" and what purpose does it serve?

Fast idle is just that. You increase the idle speed so that a proper amount of oil lubricates the turbo charger and aides in complete combustion of the fuel in the cylinders. You can idle at a fast idle for long times without causing damage to the engine or so I've been told.

To expand on Will's excellent explanation it's good to let your engine and turbo cool down for a few minutes especially if you were at highway speeds or stopping right after a climb. That's where fast idle helps.

Hey Phil; it's possible you don't have one. Assuming you have an 8V92 the high idle operates differently than on the electronic engines. On the electronic engines all you need is a switched input to the ECU and the electronics take care of the rest. On our mechanical engines the governor needs to be mechanically bumped up to make the idle go high. There are a variety of ways of doing it. According to my Detroit Diesel manual if you have a built-in high idle you will find a small air cylinder on the top and a small one on the side of the governor. An electric switch up front would then operate an air valve controlling the pressure to these cylinders. If you have the Jake Brake on your coach I don't see how it is possible to have a high idle setup since the Jake buffer switch at the governor uses the place where one of the cylinders goes. On my 77 coach I have Jakes and use the cruise control to obtain high idle.
Take a look at your governor, if you have the two small cylinders you will have a high idle switch somewhere. Without the cylinders you don't have high idle unless you have a non-standard arrangement. A non-standard arrangement would entail at a minimum something to tweak the throttle input at the governor.
everything I know just ain't so

My 77 had a mechanical throttle, it was just a short cable in the rear engine compartment, just pull on it till you have the desired rpm then twist it to lock it. Kind of a pain but cheap and simple. The 8.3 I am putting in has a cable also, but it runs to a small black box that is operated by 12v and a switch from the dash. it looks fairly simple also. I will check it out today and see if there is a brand or part number and post it on here for those who may want this option

The fast idle switch on my coach is on the right side of the dash along with other switches. It increases the idle to 1000 rpm and should be used anytime the coach sits for more than a few minutes. The primary purpose is to prevent unburned fuel from washing the oil off of the cylinder walls. On other coaches I have owned, the fast idle is a part of the cruise control function. In either case, you are prevented from engaging the transmission until normal idle is established. I would be careful with rigging a fast idle that is independent of the transmission.

Don't some of the sob's use the cruise control for fast idle?
Not sure how it works but maybe it can be used.

On my Country Coach and Alfa, the cruise control can be activated when in neutral, then depress the button to increase speed, stopping at 1000.

Hi folks, the little box I was talking about it actually the throttle position sensor, this could be made to work for a high idle. It is tied in with the transmission ecu and is an Allison part. possibly with a potentiometer or something to be able to adjust the voltage for rpms, there is a slotted cable end that is also adjustable. As stated in the last few threads it would be wise to tie it in to the neutral safety switch so it ONLY works in neutral. For those of you with older coaches this may be an option. Hope this helps
