thanks

hi there everyone

take it to the GMC forum,there you will find someone who will help you

Omni,

Your check gauges light checks for correct input voltages to your gages. I know for shure that it will light if your oil pressure shows lower than 5 psi (not sure what voltage that is at the gauge). The fact that your "rev and speedo" gauges do not seem to be working, may be the reason your "check gauges" light goes on.

good luck.

Simon, that is.
