The owner's manual for my 2002 Fleetwood Southwind clearly states
"the DC power converter will charge the chassis and house batteries
when plugged into 120-volt AC service or by the generator."
My 2002 Southwind on a F53 chassis would not start after being
in covered storage for 2 months. The coach was plugged into 120V
and the house and chassis batteries were not disconnected. The chassis
battery showed about 11.8V. The house batteries showed about 13.3V.
The engine would not start with the auxiliary start switch.
The chassis battery disconnect switch seems to work; when switched off, the entry steps do not work. When on the steps struggled but worked.
I charged the chassis battery for 6 hours and the reading was about 12.4V.
The house batteries are being charged by the convertor (Intelipower
9000 with a Charge Wizard) but the chassis battery is not. The
chassis battery shows about 12.4 volts with the generator running or
with the coach plugged into 120V. The chassis battery shows about 14+ volts with the engine running.
Any body have any ideas where I should begin?
