I crawled all over underneath the camper and traced where all the wiring goes.
Here what I found ..
Refer is not connected to converter at all, The wiring to the refer went all the way to the front hitch but just hanging there. Someone in the past cut up the refer wiring near the front hitch so I have no idea where was connected to but I am assuming it was connect to the car or truck pulling the camper so refer can run while it being towed.
Look like if I wanted to use refer then I will have to use the propane instead or use a battery and a battery charger to keep the voltage stable.
But there is a good new, I found the short in the wiring. It was the wiring to the water pump. A rat or mouse chewed on it. After I replace the wiring the converter should stop tripping hopefully.
