[quote=patrickt;1388260] take the handle of your screwdriver and whack the voltage regulator and see if the needle wiggle stops for a second (or more). QUOTE]

Sage advice from our electrical expert.

Mine was doing the same thing. Turned out the diodes were shot in the alternator.
Had it rebuilt for 100 clams and now it works perfectly again.

My ammeter needle started waving at me and the red charging lamp above the ignition key switch started flickering intermittently. Looks like I have an electrical gremlin to sort out. Ugh.

So, if we combine Patrick and Rick into one author/source, would we call them Pat-Rick or should we just shorten it to P-Rick?

Relax everyone, just had a funny idea.

Ehhrrggg.

Don't SPF cars have that funky issue on the source of the 12v line for the voltage regulator coming from a flaky source? As I recall, it's a really easy fix. Antny should check that out first.

Good to know! Thanks. Anyone have the info on how to address this? Why would it happen all of a sudden? Does something change over time to cause this issue? Thanks in advance!

Anybody? Anybody? Anyone know where I can find this info?

Shoot Blas a PM and ask him. He knows more about the SPF wiring than most, and has wiring diagrams as well. As I recall, certain SPF cars took the source voltage for the voltage regulators from either a bad connection or a spot in the circuits that did not accurately reflect the system voltage. But that's just from memory, and I don't own an SPF anyway. And that may, or may not, play a factor in your problem. If you had that problem, though, I would fix it first. Then, if you still have your charging needle goofy behavior, we'll lead you through the diagnosis. It is not difficult.
