Went out to the coach to check a couple things out. Tried to start the generator; completely dead. No clicks. Completely dead. Thought I’d try to start the Aqua hot diesel, same thing. Nothing. Coach has been plugged in to 50amp since October.
Checked batteries with a multimeter. House 13.4V. Chassis 13.2V
Started the coach. Started fine. At 1000 rpm. House 13.6V Chassis 13.4
With engine on, generator stared right up. Engine and generator on. House 13.6. Chassis 13.4. Aqua hot also fired up with no problem.
Turned coach engine off. Kept generator on. House 14.45V. Chassis 14.56. Held those number now for about hour, running just the generator.
Other info. Charger/inverter has been acting weird for the last year, including dead control panel. Last time I used the generator, in October, I did notice it started slowly, but I didn’t think much of it at the time. Chassis batteries about 3 years old. House batteries 1.5 years old. All house lights were normal (ie, no indication batteries were low or dead.
Question: 1. What are your thoughts. 2. Does the generator charge the batteries through the inverter/Charger or does it charge the batteries directly?
Thanks in advance.
