    I turn my lights on, top front marker lights on trailer work, blinkers work and brake lights. Nothing else. I've tested the plug at the truck. Black wire has power, Brown does not. I've changed both switches, lights and interrupt. Any suggestions? Running a jumper to get by for now.

    Try the breakers in the middle of the fuse panel....put a jumper wire on it or test light.

    Had kinda similar problem today, blinker and 4 ways stopped. Had power to ssitch on steering column, and could hear relay clicking . jumper the breaker, nope , not it. Replaced the relay....gotcha sucker! Just worn out i guess
