Lights are all mounted. Problem with grounds. I mounted the front lights on the spacer between the bumper bars but I think my ground problem is in the bumper end bolt area, or maybe where the bumper mounts attach to the frame. I HATE electrical work! So, I am trying to track my ground connections from the frame to the lights. Head lights and tail lights work fine so I assume that I am loosing continuity somewhere between the frame and the mounting on the bumper end bolts.
QUESTION? Is di-electric grease a conductor or an insulator? I was always under the impression it was a conductor, put it on my battery clamps and a thin coating on the light bulbs to reduce corrosion and make a better connection. Recently a battery guy said I was wrong, it was an insulator and would weaken my connections.Cold here today. ??? tomorrow.
