One Headlight out - Need help diagnosing

Apr 10, 2006 5 Replies

My '73 Super's driver side low beam is out. It was off and on last summer. It worked when it felt like it. Some times if it was out, I could feel down to the fuse and jiggle the connection and it would work. I pulled the connection and cleaned it with sandpaper plus added some dilectric grease on the connection with no avail. I'm going to try a new bulb this weekend. Anything else I should try before attempting to replace the wire? BTW, does anyone know what guage wire the lights use? Thanks.



Don't replace the wire; wires don't just go bad. Worst case: check the crimped on end terminals and replace those if needed.

Replace the fuse for that beam (there are 4 separate fuses) even if the fuse "looks" good. And polish the fuse holder ends as well. Remote possibility is that there is some fault in the fuse block itslef (loose rivet, etc.)

I agree with Jim and I also recommend pushing the fuse contacts closer together to make a stronger connection. ;-) Check the ground wire for the Headlight. It should be located near the fuel tank secured by a screw.

Thanks guys, I'll give it a go this weekend. The electric portion of auto repair is not my strong point.

and I would suggest Halogens.
