Have no 12 v power even with shore power hooked up. All the 110 power is normal while hook up to shore power, or gen. Converter is humming like normal, just no 12v power. Checked all connections, fuses, and breakers, everything normal and good. Just wondering if it is the batteries.

If you have a volt meter, start at the batteries and work forward. Might be something really simple like a loose connection at the battery disconnect switch.

I say to disconnect all Battery Cables. Noiw test the Voltage, should be around 13 Volts DC.
Now get you hands on a DC Load Tester and check each Battery. You may find a dead cell

Definitely sounds like your battery could be bad. Can you bring the battery all the way back up 100% with your battery charger? The easiest thing to do would be to pull the battery out and take it to be load tested. Then be prepared to come back with a replacement if it fails the test.

Considering the number of batteries you may have and their weight, it may be more logical to buy a load tester. They are not very expensive compared to a strained back.

Well said Chester. I'm sitting here recovering from a herniated disc after many years of abusing my back.

I have a much used one of these;
Battery Tester - Save on this 6v/12v Battery Load Tester (http://www.harborfreight.com/100-amp-6-volt-12-volt-battery-load-tester-90636.html)

I'm sure that there are others out there. Easy to tell if there is a bad cell, just follow the directions and look at the meter
