Temp gauge / new Alternator

I'm having a weird problem with my temp gauge after installing a new alternator.

The temp seems to fluctuate rapidly... a few high RPM and the the temp goes to near hot, idle a few minutes and it goes back to normal, you can watch it move.

Unhook the alternator and the gauge acts normal, might slightly fluctuate but nowhere near the amount it does with the alternator working...

It's a '68 with factory console gauges, with the temp wire going into the harness on the drivers side, along with the alternator wires, all very near the alternator.

Any Ideas?

Re: Temp gauge / new Alternator

Sounds like your temp gauge wiring is getting some noise from the alternator. More than likely, you need a better ground to your console gauges. Did you hook up your ground straps to the engine?

Yep, ground straps are hooked up.

Hmmmm... better ground to the gauges, huh. The gauge does not change instantly with rpm, would noise affect it that way?
