Hey Everyone,

I recently had a problem with my headlights. The driver side headlight was very dim while the passenger side was normal. After a lot of investigation, I found that the fuse was not making good contact. All of my fuse holders/connectors seem to have a bit of build up on them. My question: How do you clean them? Should I just replace the fuse box? Any input would be great!

Thanks

 

Headlight connectors you should be able to replace, they sell the pigtails at most auto supply stores. Does it still use glass fuses? I so just take a bit of metal polish or something that will remove corrosion.

I had to clean up the contacts on the gauges for my 72. Metal polish, q tips and a lot of time did the job lol

 

I had trouble with the connectors on the fuse panel in the 77 I had, I ended up taking it out and soaking it in vinegar.

 

Update: I have since replaced the headlight pigtails. I found that the passenger side one was cut and damaged. I just replaced both to be safe. I found them to be one a few dollars for both.

I will try to use the metal polish next.. I will update soon.

Thanks for the input

 

Hey Folks, Well after cleaning the contacts I am still having an on/off problem with my headlight being dim. The only thing I can think of now is to replace the fuse box some how. Has any one replaced their fuse box? Upgrade the fuse box?

Thanks

 

The problem is going to be in the wiring. Wire a relay and use the stock wiring as as trigger so you can run full power to the lights.

 

Definitely do a relay, especially if only your headlights are affected. It's super easy to wire and will solve the problem.

 

That and clean up any frounding points. Everything grounds through itself on these trucks. Lights ground thru the light buckets and brackets.

 

Thanks for all your input guys! I am not sure how to wire in a relay? could you guys help please? I was also thinking of installing a in-line fuse link. I would do it right behind the fuse box. I would get power from the main and jump across with the in-line fuse link to the single wire ( basically replacing the glass fuse and contact points) I would do it for both headlights / I would be taking the place of both glass fuses and contacts with the in-line fuse link. Would this work ok?

 

Problem isnt in the fuse, its guna be the corroded wires amd connectors.

Switched power is the stock headlight wire. To acc wire is new wire to the headlights

 

Update: I found the fix. I fixed it by installing an in-line fuse. I was only able to do one (driver side fuse) as the auto parts store I went to only had one. I will be getting another one today. Here are some pictures of what it looks like! Please excuse the poor pictures as i did it last night after work around 10 pm.

What I did was I took the single wire for the driver side headlight and installed the in-line fuse to the large power wire for both headlights. It seems to work just fine and both light are super bright now.

Thank You all for all the input!

 

Did you run new wire to the lights too?

 

No new wire was ran, I basically just jumped the fuse on the back side of the fuse box where i installed the inline fuse.

Thanks for giving me the relay diagram.. I will keep it in my important electrical stuff lol
