My gauges have been acting a bit goofy lately. Lots of bounce and jiggle in the fuel, alternator and oil pressure gauges, especially when it is hot. Is there any "master ground wire" that supplies these gauges that might need cleaning?

I have my gauges out at the moment...possible that these you mention are all located on the vertical right plug (on back of cluster) mine had some light corrosion. I have not found a master ground (otherwise I would clean it) Three plugs of about 15 wires each on back of gauges.



These wires are not easy to trace, either.
