    My volt guage went out recently, and I'm trying to find out if there's a way to test it out before buying a new one and finding out that didn't cure the problem. I thought I was missing one of the metal clips to make the electrical contact on the instrument cluster, but turns out all of the clusters I found in the junkyard don't have this clip. Why a hole was made in the cluster if it never used a clip in that location from the factory is news to me. I may have to check my sending unit too.

    I think you can run a continuity tester between the leads. If that doesnt work get a 6 volt latern battery and connect it up, should read half way to the twelve. Run two in series(?) and you can make it 12 volts.
