Oil pressure/volt meter troubles

Postby monzacoupe » Mon Sep 04, 2017 9:53 pm

Hi all, I have the dual oil pressure/volt gauge in my car, what would be the most common reason that it's not working? It is seated properly into the dash and I couldn't find a fuse specifically for that gauge in the box. Bad connection or broken pathway on the circuit board in the back of the gauge cluster? Any help is always appreciated.

If the other small gauge(temp), and the idiot lights work, then the fuse would not be the problem. First question is, did it ever work? One thing that comes to my mind is if someone swapped a Spyder gauge cluster into a base model car, the wiring would not match up.
If the needles used to work and now they don't, it very well could be a broken trace on the circuit board, most likely the ignition + feed.
