gauges go nuts

Howdy.. I have a gauge problem that just recently showed up...
When I start my car ,the gauges all read strangely...some high some low.
When I turn on the headlights, they all peg!! Put on a turn signal ..the speed-o pulsates! The battery and alternator check out fine.
The car is a 3 year old '31 model A coupe-rod 350-350..with a 70's GM tilt column,Autometer gauges, single wire alternator and Painless harness. This thing is driving me nuts!! Can anybody help??
thanks...uncle dave

First thing I would check with a VOM is make sure you haven't lost a ground on the body or to the gauges.

Have you checked to make sure you have a good ground for the gauges. Sounds like they may all be grounded to one spot and your not getting a good ground. I had a similar problem on a stock blazer, replaced a bad ground wire and it went away.
