My dash gauges drop out to zeros. Oil pressure, battery, temp, and gas gauge. It acts like a short in the grounding system. Located on the right side possibly.

Hello,

It sounds like you may have a bad connection at the cluster, remove it and try unplugging it and then plugging it back in again.

Here is a wiring diagram (BELOW) and some guide to help you do some testing of power and grounds to help you get the problem fixed.

Please let us know what happens. I am curious ;)

Cheers, Ken
