House charging system issue
Batteries at 9.6v at all times ( even w/110 AC hooked up, or engine running)
Water levels good
Sequence of events:
Parked but failed to hook up land line for 2 weeks.
2 weeks later, found no 12V lights, so attached AC and got them back
1 week later, doing scheduled generator/HVAC test. Generator wont start. Checked house battery voltage and water levels.
Shouldn't I get charging voltage (13v+) at the batteries when AC is plugged in or the engine is running?
