I am towing a boat with my 2000 Discovery II. The lights on the boat work with my other vehicles but on the Disco the passenger side blinkers and brake lights won't work. Used a multimeter and the juice is there to run it. I've changed bulbs, rewired the Disco harness, boat harness, did a rain dance and prayed to the trailer gods but to no avail. Anyone have a clue what I've spent all day missing?
