Re: 1986 C10 Voltmeter

The voltmeter also shares a pin with the dash illumination ground circuit - so if you have dash lights and the rest of the gauges are working, the problem most likely exists within the cluster.

Check that the clips that the gauge stabs into are tight to the studs. On the back of the bucket, make sure that there is a good clean/tight connection between the clips and the copper conductors on the PC board.

Thanks! I'll go outside and try taking a look tomorrow. If worse comes to worse and I have to run my own wiring to the gauge, is it okay to run it to any 12v ignition wire?
