I'm not real good at electrical.Onan 7500 Generator problemI have a 2006 Fleetwood Bounder 39z While running the generator on the way to a campground the generator stopped putting out power to the motor home. The generator starts right up and runs but after a few minutes it drops rpms like something is pulling power. and I am not getting any power inside. When I connect to shore power everything works fine. I've checked all the breakers and fuses. I did notice now that my inverter is making a humming sound and the cooling fan keeps kicking on. Any Ideas as to what could be the possible problem.
