My turn signal works fine until I turn on my head lights. When I turn them on, weird things happen. The left turn signal no longer blinks, and in addition to that stepping on the brake pedal not only activates the brake lights, but also activates the front side marker and turn signal lights. I did not visually see any obvious bad spots in the wires anywhere, but I don't really know where to start after that. I know how to wire things up to make them work, but I haven't a clue on how to track down wiring gremlins. I do have a multimeter and a test light, but don't really know what to do with either of them.
