Elect --- no lights and dash gages drop out
Not sure if in the right spot, all marker lights and parking lights not working, no blown fuse and relay gets hot. all dash gauges go nuts, off & on any time you turn on a fan or ac, use elect window. rear view go off & on. if you turn off all controls gauges go back to were they are? when I took to rv shop all was good would not act up, went home and all went nuts till I turned off all other controls.
any help will be great
