Amp gauge going crazy...help.

Ok. This one is stumping me. When I start the truck the amp meter in the dash is stable and everything is fine. But when I turn on the turn signal, or hit the brakes, or anything else that draws a current, the needle on the amp meter starts bouncing from one stop to the other (waving at me). I have checked for continuity in the wires and all seems fine. The only thing I noticed is that the voltage out of the alternator fluctuates by 2V when the blinker is on. The alternator has been rebuilt. Does anyone have any experience with this? Any suggestions where I should look next?
