Problem starting Generator with House Batteries
I have a new Chateau 25v and am having a generator problem. After using the house batteries (2) overnight they seem not to have enough power to start the generator. The generator cranks slowly for one or two tries then will not turn over. If I start the coach, the generator cranks quickly and starts easily. I checked the batteries and they test as new (600CCA). The charger is putting out 13.6 volts. I have taken the cables off and put them back on to ensure a good connection.
At night I only use the led lights and a vent fan, so the batteries should not be drawn down. All the other 12 system seem to work fine. Could it be a weak ground?
Any suggestions? Thanks
