Use a 6 volt test light w/a long wire, assuming that your car has positive ground, connect the light to battery negative and use the long wire to follow the ground path, start at the frame, next to the bumper bracket, ...................

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.

Di-electric is an insulator. While it is good stuff, I would start by wiping it off every where you put it and try again. You can also run a jumper wire from your lights to a good ground point and test your lights. This will tell you if each of the lights have a decent ground.

Some products are conductive with aluminum or copper powder in them. I would avoid these as they can cause galvanic corrosion. A true dielectric is nonconductive. The electrical connection is metal to metal. The dielectric is best applied before connecting to provide a moisture barrier to prevent corrosion. The dielectric is squeezed out from between the connecting surfaces and will not interfere with conduction.

Note that most paint insulates and must be cleaned off connecting surfaces.
