Onan mobile Gen Set HDCAB/HDCAA start problem
We have a 2003 Monaco Executive with a generator start problem. I am able to start it by running the engine for 45 minutes and using the battery booster. The chassis and house batteries read high 13's...

Voltage at the back of the generator reads 13.6. When DH tries to start it the voltage drops down into the 9's. House batteries do not drop voltage when attempting to start.
