Gauge light question
i took my cluster out of my truck because none of the gauge lights were working, we checked it and they are getting power and i checked and changed all of the bulbs but when we put everything back in my truck they still don't work, any suggestions? i was thinking of using the led strips that i have seen other guys use on this website, thanks

Re: Gauge light question
Maybe broken ground connection in the print. How did you check them? voltmeter on the + ,and - lead to chassis. Or did you measure connection trough the bulb socket? If you grounded on the chassis you will only know that you have power, - might still be missing and your lights will not work.

Re: Gauge light question
YA Im having the same problem. Gauges work but not the lights. If I figure mine out I will be sure to let ya know where my problem was. I have bought lights and a headlamp switch but been busy on the rear end at the moment so I havent had a chance to to look yet.

Re: Gauge light question
Woohoo I fixed my dash lights. After checking broke grounds and finding no power to the grey #2 wire on the plug. I finally decided to clean a ground I had been looking at the whole time but just kept looking for another issue. And wam, on come the dash lights.
