I have three batteries in my class A. Two of them are located under the steps. If I am right, these two are the house batteries. But, of the three, Which battery is the aux battery? Is it the battery that is located under the hood, which is charged with the Alternator and is for starting the Engine? The instrument pannel on the dash has them listed as MAIN and the lower AUX.
The main battery is typically the engine battery, while the Auxillary - or Coach, or House, or house battery seems to be the one under the steps.
Only the coach battery is recharged by the battery charger from 110 volts. The engine battery is only recharged by the alternator when the engine runs, or can be recharged by holding the switch that says AUX start, and that will energixe a relay that connects the coach and engine batteries together, so both can be recharged while holding down the switch. Or you can use the AUX start switch to give the engine battery some help in starting the engine.

Thanks for your answers.I looked this morning and the AUX batteries were down to 10.22V. I wanted to put some gas in the MH so started it and drove about 8 miless to the nearest service station and back. I then checked it again. Both the main and aux were at 13.65V. I shut the engine off and started the Generator. (the gen set was harder to start this time). I let the gen set run with both air conditioners on for about 35 minutes. I shut the gen off and could see the AUX dropping. Right now, about two hours later, the main is at 12.85V and the aux is at 11'25V. I added distilled water this morn. They were low. The main battery is self maintained, so dont know about it. I am going to hook back up to shore power,15 amp. I need 50 amp to run everything but am only going to have enough to charge the batteries.I'll keep you informed. Also plan to check the solar pannel to make sure it is clean.
15 amp should run the converter.. Note SHOULD some can suck 20
Minimum charge time on batteries.. This assumes your converter it up to the task, is six to eight hours for a full charge. Of course if you settle for 80-90 percent you can get there in 1-2 hours
I did plug it into 15 AMP from house. I have a long heavy wire that runs about 30 feet then I have to use a 30 amp pig tail to another pig tail which plugs into the 50 amp service cord. As long as I dont use any thing else it does ok. The batteries are up to par now. I plan on another 4 hours.
