Voltage Regulator

[fmfarrisjr]

When driving my D24 Dodge (6 volt), the voltage gauge indicates charging is constantly taking place. The needle really never just settles in the middle. Is this normal? Does this indicate the need for a new voltage regulator?  The needle swings between the center and extreme right.

Have you done a voltage check on your battery with the car running and also with the engine turned off?

as the ampmeter is just a visual tool to show flow of current your unit could or could not be anywhere close to accurate as basically none are calibrated.  The are built to deflect X distance on the gauge for max amp rating shown on your gauge scale.  You could well be running normal and the only way to determine that is placing a second amp meter inline with the battery and verify the actual charge/discharge rate of your dash mounted indicator...again this things are not accurate nor are they exact linear BUT...you should not be bouncing around a lot either..have you checked the very wire connections on the meter or regulator.   If the test installed meter bounces also....I would look to the dirty contacts and loose connections.

I had the same symptoms. Had the guy that rebuilt my generator check it out. Reg was bad. Replaced and gauge reads steady now. Got mine from The Brillman Company.

agreed had the same issue.  Generator was fine, regulator needed the airgap adjusted. Fine

I had the opposite......replaced the regulator....no improvement.....ended up being a burnt spot on an armature (or something like that).  Rebuilt it and its fine.
