Upper Clearance Lights Out

[solds88]

    Try this technique to narrow your search. Safety first, remove the TT power by unplugging AC and disconnecting the battery. Using an Ohmmeter, connect one lead to the plug or some other predetermined point in the circuit. Connect the other lead to the frame or trailer body and look for a low(er) resistance reading. Have a helper watch the meter while you tug wiggle and twist the wiring. If you're lucky you'll be able to see the meter change values when you hit the right spot.
