Light Bar Repaint Question
 

Removed, repainted, and tonight I'll reassemble my light bar and horn assembly tonight. Before I do this, an item came to mind and wanted to ask the people on here from past experience. I just remembered the bar probably serves as the positive ground for the lights and horn?? Do I need to sand off paint in any particular area to ensure a good ground on the headlights and horn? I wasn't sure whether that or the bolts when they tighten on the fenders and on the headlamps provide the "good enough" ground for these items.

Just did the same thing last week.. I did not sand any areas but I did clean the bolt holes well as well as the threads on the bolts themselves. I then used Loctite Copper Antiseize 8008 on the mounting holes and bolts. This antiseize is advertised as being highly conductive. When I checked the ground it was very good.

ahirt has a good solution. The method I use is to clamp a wire to each conduit inside the radiator shell and run to the forward hood latch screw under the frame. Use a star washer to cut through frame paint. Eliminates the bar and fenders completely.

The horn does not depend on a ground path thru the headlight bar. I always run a separate ground for the headlights.

I had the same issue, headlight ground I mean. I usually wrap some copper wire around the bar-to-fender bolts before putting them in. An old farmers trick ... on old tractors the rear fender lights always failed. We simply jammed a copper nail between the fender and the rear axle housing ...

Thanks All for your suggestions - Success!! Took a bit of each suggestion. After painting, when reassembling, used star washers on the fenders, used some copper wire to wrap on bolt, and copper antiseize. I will admit I was initially worried it wouldn't work, but when all tightened and the switch thrown - all lighting worked, and horn still operated - thankfully no broken wiring!
