I would check the 12V feed and ground. Lots of places under the dash tha you think would be a good ground, isn't. Make sure your feed voltage is not from a source that varies like the dash dimmer etc. If you dont have acess to a meter run a couple wires straight to the battery, that way you will know if you have gauge or connection problems.

so we ran i line to a spar battery that we had in the garage and hooked it up to that and the gauge steadied but then when we went and hooked up the the truck battery it started shaking again so then we unplugged the alternator and the gauge steadied again we checked the charging circuit and everything was fine so what can i do to make it so the alternator doesn't make this happen??
