Had a little light flicker at idle, goes away underway, Tightened the alternator belt--no help.

What else could be causing this?

Thanks.

My 67 did this about a year ago and it was a faulty voltage regulator but it can also be caused by other problems.

You could try a new voltage regulator, but I suspect that the real cure is to install a high output alternator.

Dang! Just when I got used to being "strange", I became a "newbie". So what the sam hell is that?

your ckt brk in headlight switch may be getting old or overloaded. it is a bimetalic strip that opens when current gets excessive and after cooling off goes back to normal position. if either small overload or aging it will cause lights to flicker - have you added any special lights to your car? you will probably have to replace your headlight switch as it will continuously get worse.

I had the same problem. The bolt that holds the ground wire on the Voltage Regulator was loose. I tightened it up and problem fixed! Thanks!
