Hello, I have a 1992 gmc Sierra 1500 slx. I just recently purchased it and I have noticed strange behavior of my gauges. All of them consistently read low except the fuel gauge that always reads past.

Asked by Dec 25, 2014 at 01:00 PM about the 1992 GMC Sierra 1500 C1500 SLX Extended Cab SB

Question type: Maintenance & Repair

I have tested the voltage at the alternator.
14.10. Also tested at the pdp on the firewall
14.8 still reads 12 on the gauge. And oil
pressure and water temp read low still.

If the fuel gauge reads past empty all the time as well as the other gauges reading low it sounds like a bad ground at the instrument cluster. HTH. -Jim
