i would ohm the wire from the distributor to the gauge cluster, then ohm the grounds, check the connections at the gauge, if all checks good i would try another gauge. i have a similar problem but only when i turn my lights on so its likely a bad connection somewhere.

Go to the junkyard and pick up a old tack pull your instrument cluster and exchange
