My 6 volt voltage regulator contacts make a racket at low idle upon startup. You can here them clicking through the firewall. Amp meter shows discharge until I rev engine up. Generator is recently rebuilt, voltage regulator a little over a year old, new wiring harness, fan belt new and at correct tension.
Also, the voltage regulator will drop “off line” frequently when the rpms drop.
Car has no modifications.
This is a recurring problem. I’ve gone through about 3 voltage regulators in last 7 years or so.
I would like to find out what could be causing this before I purchase another “premium” voltage regulator.
Thanks,
Curt

i know on the older ones you had to adjust/set the regulator for cut in cut out, same for the generator output, had to adjust and set that as well.

I have had dozens of GM cars with the voltage regulator mounted to the fire wall and have never heard a click.
I suspect the problem is the manner in which the regulator is attached to the tire wall. Are the rubber insulators in place and is the rubber still soft....or is there direct metal to metal contack between the regulator and fire wall?
At idle it is normal for the ammeter to register discharge as a geerator is has no output at idle and the cuy out in the voltage regulator opens up as it is supposed to do at idle or when engie is not running.

Well, I stand corrected.
I just started it up and listened carefully.
The clicking sound (very slight) seems to be coming from the bell housing area, NOT the voltage regulator.
I assumed it was the voltage regulator-I assumed wrong.
Now I got to figure out what is causing the sound from the bell housing area. It’s not at all bad. Could be the clutch stuff. Who knows? It works fine. Not going to worry about it.
Thanks for your thoughts Gene.

Before I was rich and could afford expensive tools like the Harbor Freight $4.99 Mechanic's Stethoscope I used a 3' piece of heater hose to help find the source of a noise. If I thought it was a bearing or gear I would stick a length of wooden dowel or a long screwdriver on the part that I thought was noisy.
