We have not experienced any issues of any kind with electrical stuff until this morning. after two nights dry camping we had a dead AGM chassis battery. There was not enough available amperage to start with just the boost switch and a dead chassis battery. The house bank is 460 amp hours so easily started the generator. The combiner looked like it worked properly, was disconnected before starting the generator and connected as soon as it sensed the charge current. After a few minutes of throwing charge into the chassis battery it would start using the boost switch. Once started the alternator provided charge for both the chassis and house banks. A few miles of driving and the chassis battery easily started the engine again.
The issue is, where is a big enough parasitic draw to discharge the chassis battery in just two days? I checked the electric choke (seems to work properly - no draw with key off and the expected 12+ vdc with the key on), and the AC clutch and both appear to be fine. No lights left on, key not left on, fan off. So far I am stumped and certainly open to suggestions!
