I was at my MH today charging up the batteries while I was doing some other things and had the generator running for 25 minuets or so the it sputtered and shut down. I tried to re-start it and it "clicked" like there was not enough power to re-start. I tried to start the motor and there was nothing!! I don't know if the alternator on the generator is working properly? Any suggestions? It's a power system 7kw with a Kubota motor.

Hi BigJerry,
You are going to need to get the batteries charged first. Put an external charger on the chassis battery and charge it up. Then do the same for the coach batteries.

On the generator there is a circuit breaker. Make sure it is not tripped.

Next take a meter reading on the coach batteries. Start the generator. Take a meter reading on the coach batteries. If it is the same, most likely the BIRD system needs to be looked at. Will the HVAC system run? If so the generator is doing its job and the Automatic Transfer Switch ok in the normally closed position. The converter may need to be looked at. With the generator running take a reading on the power input leads (120V AC). Then take a reading on the output leads (12V+ DC).

Take a reading on the engine batteries. Start the engine. Take another reading on the engine batteries. If it is the same, the engine alternator may need to be looked at.

Is there shore power available? Dumb question but I have to ask, is there a least 1/4 fuel in the tank?

Thank you for the tips on what to look at. I'm going to have to replace one of the batteries first. There isn't any shore power available and I believe there is more than a half tank of fuel. I can't say for sure since the gauges reset when the coach turns over. When I parked it 2 weeks ago it read a half tank.
