check your ground cable going to your chassie they rust and lose contact that was my problem when I had same problem.


When it comes to 12volt systems, the ground is the first thing I check. Like the car, your lights start acting crazy. Remove the ground to the chassis and grind to bare metal. Add some deox to the bare metal and reinstall the ground.

I do agree on the volt meter. I also use this to check the shore power before I plug my trailer in.
