i take it you have some experience with bad grounds...
i agree by the way.it's a classic ground problem.
problem being...the other flood works fine.they both ground to the same body section,that being the ambulance box.so...box to frame ground path is fine,frame to electrical is fine.threads on bad flood mount are clean.going to install the flood on the bad side and check ground from the light to the body.
what would happen if i had a short in the power wire to the body,active only when the switch is thrown, aside from a spark or two?(just thinking)
Our work day has been cancelled due to high winds,so i can go get that test light.and some more paint...color change in progress.
thanks for the tips.
