Just purchased a 2013 Roadtrek RS on the 3500 chassis. It has 2 6 volt agm batteries wired in series under the hood for the house batteries. These batteries are constantly drained and will not start the generator. When I plug into shore power, the batteries charge and the generator will start, but the batteries don't seem to be charging while the vehicle is being driven.
The parasitic draw with the battery switch off is 0.5 amps. When I hook shore power up, I am getting about 14.6 volts across the two batteries. When I remove shore power, and start the engine, I am only getting 12.6 volts, which is also the resting voltage of the battery bank. Hence I am not getting any charge from the alternator (correct?).
I'm guessing the Eaton battery separator is at fault. Do I just replace it, or is there a way to actually test the separator? Is 0.5 amps enough to drain these batteries over 24 hours such that they won't start the Onan generator? Any other suggestions?
Thanks!
