went over there today and tested the current to each wire, and it seemed good. The issue probably is the ground, because he has almost everything powdercoated up there, and it's probably messing things up. Not sure though, because we can get one filament to light up,(the dim one) but not the bright turn signal one. The same filament lights up on both the parking lights and the turn signals. Go figure.
I'll post more when we fortify the grounds. car is still doing some strange things, like the parking lights working even though the grille wasn't even on the car. It shouldn't work at all if it's just sitting there, should it?
Also, we have a very small constant power draw through the horn wire (about 0.02 volts) Can't figure out how that's possible either.
