So I checked voltage and I have 10.46 on each of the batteries. Sounds dead, right? When I turn on one little ceiling light and the little porch light it drops to 9.95. However, when put on the battery charger (completely out of RV) they appeared to charge easily and indicated a full charge. (Obviously not correct). As a point of reference I checked the engine/chassis battery and it read 11.88 without the vehicle running. Does this give everyone some ideas of what might be wrong? I really appreciate your help. Thanks!
perhaps a shorted cell in one or both of the batteries. This would explain why the converter fan was running constantly but the batteries weren't charging. converter trying to raise voltage across batteries to charge but shorted cell just causing battery to heat up and not actually charge. Also be aware your vehicle battery seems low too( under 12v) . might want to throw the charger on that as well
