    Huh?????? So are you saying it wasn't actually broken and that your test method was showing stray voltage? I'm confused. I dont have any wireless testers in my toolbox. The old tride and true multimeter works the best. Power probe doesn't lie either.

    On chassis node equipped trucks they do send out stray voltage when off. Sometimes the led taillights have a very faint glow. Incandescent taillights will not. Normal operation.
    Old school bulb test light for anything 12v because it actually puts a load on the circuit.
    Multimeter for everything else.
