VoltMeter Needle Dancing
 

OK while at idle when turn signal is on my voltmeter needel ticks with the turn signal. Any idea on what is causing this?

Might be normal, my 84 suburban does the same thing.

This is a normal condition every chevy truck iv'e owned has done this.

Mine does and I have Autometer gauges. It's normal.

mine never did.

Depends on the load (a/c, stereo, etc.) but mine does it.

You need a damping circuit on those to keep that from happening.
Chevy is not going to put one in for us!

So once you put a damping circuit for the voltmeter, what exactly would you like it to show? 13.5 volts constantly? Might as well just glue the gauge needle solid.

Cool I won't worry.

Mine also does it, I also have autometers.

Needle bounces with sterio too, depending on the sound and amp draw.

I need a higher output alternator.

Electric fan and headlights together make my headlights kind of dim. Drives me crazy.

mine never did dance at all. my load includes a sony cdx-mp30(mp3 player), a 600 watt amp, a 12, stock gauges, the cool blue type headlights, grounding problems so the park lights work but the blinker part doesnt, plus the battery was about dry so might be a grounding problem or the gauge who knows
