gauge lights 70 GMC
Some of my lights dont work. The speedo light does and one of the fuel lights does but the rest dont including my left turn light. I have pulled all the bulbs and checked them.. Whats my next step? Replace the wire board on the back of the gauges? I started to pull the dash panel off yesterday but decided to wait since the weather dropped and my only other vehicle is my Harley.

Re: gauge lights 70 GMC
If the bulbs were good when you checked them. You could try cleaning the contacts on the holders. I used some fine emery cloth to insure good contact. If you can see the circuit and it has some built up crud you might try a pencil eraser to brighten it up. I would try that before I replaced the circuit board.

Re: gauge lights 70 GMC
I might do that. At 4 bucks for two bulbs changing them all will get kinda expensive.

Re: gauge lights 70 GMC
I got them at Advanced Auto. I think I will do some shopping around to find a better price then.

Re: gauge lights 70 GMC
When you have the sockets out check them with the bulbs in them with an ohm meter. I have run into bad sockets that don't work even with new bulbs.

Re: gauge lights 70 GMC

This would look sweet in the dash.

Re: gauge lights 70 GMC
Kevmic check out this thread:
http://67-72chevytrucks.com/vboard/s...inting+needles I just did it to mine and am very happy the way it turned out. Also, i now that someone mentioned about taking very fine sandpaper and sanding the traces on circuit paper. I had to do that. I went out and bought 6 new bulbs and it turned out that i only had 2 bulbs that were blown. The sockets were the problem. What I did to fix that was sand them as well. There are 2 tabs that actually make the contact with the circuit paper, I sanded those. I also sanded the inside where the actual bulb makes contact with the socket tabs. Good luck. Hope this helps.
