Hi,
One thing that could cause this...
Check the wire which runs from the warning light to the D+ terminal for a short. If there's a break, and it earths out then the light will stay on.
You could try running another length of wire to by-pass it to see if that's what the fault is.

is it 6v or 12v as the 6 will tend to stay on and dim at revs
just had mine done new gen and reg and it still does it

Hi paul,

Your diode from your alternator is probably broken because you mixt up the wiring ( I think that because I was reading also your other topic about the wiring) A VW is alway's with - on the ground, check first the bleu cable that starts at your alternator, that bleu cable go's to the regulator and from there to your light, you can check the cable with a ohm meter!

I recently replaced my voltage reg and generator, and for some reason at less than 1000 rpm, i hear a click in the regulator and the light comes on, then sometimes won't go off until i hit about 2000...

not so much lately, but it was really bad when i first did it.

Maybe it's just corrosion on old wires, and you aren't getting a good ground.

That has also happened to me. I've had electrical problems, and sometimes just replaced/fixed a corroded terminal or something and helped it.
