Loose contacts in the generator/inverter transfer switch causing inverter to pull more load. If it is the main 120 Vac breaker, the DC battery kill switch will have nothing to do with it. Does your coach have a shore line to generator transfer switch that may have loose contacts or be drawing too much current in the transfer? Invertor delivering too much current? the main is a 40a breaker. i have replaced the original inverter with one about double the original one. and i will check out the second part of your response. thank youRe: Dash AC blows out of the defrost vents Krusty wrote: Yes, its a vacuum leak. Have a look under the hood for a vacuum reservoir. Test it for leakage. You will need a vacuum pump for testing. Also have a look at any vacuum lines for cracking etc. You may have a vacuum check valve near the reservoir. Test it as well, when they get worn, they don't hold vacuum well. thanks, will do.Re: main breaker breaks when i shut the generator off.
