If a just start the A/C or the microwave without another appliance running, then shut that appliance off, the generator cuts off. As long as there is a load on it, it continues to run. As soon as the load is removed the generator cuts off.
Problem 2: The 5th wheel has a new battery, or so the previous owner told us. We just got it over the weekend. The battery looks new. I have not pulled it out to check the manufactures date but will. I'm experienced with charging systems and such, but not with the electrical system in this toy hauler. The battery is low I presume because it is not getting a full charge from the converter. Even when the generator is running the 12volt lights are dim but do brighten for about the same time the converter cycles on then go dim again. I can hear the converter cycle on (fans turns on) when the lights get brighter. Seems to be the same when connected to shore power.
OK, here is what I think.
Problem 1) Dirty Carburetor - remove bowl and clean your idle jets.
Problem 2) Bad Battery
a) Previous owner "fibbed" check manufacture date
b) Broken plate in a cell shorting to opposite plate - could be due to a single shock or cumulative shocks from any vertical "G" source.
