I took the alternator apart cleaned everything and put it back on. I noticed the shaft is missing the key that keeps everything
in position so I tightened the nut down real good. I did not notice anything moving out of place. Belt has 1/2 inch deflection.
Now when I check the battery the charge is 11.87 and with the engine running it shows 13.87. The light is still on!!!
I replaced the regulator, so maybe that is not the problem. We were thinking the charge running should be 14+, so maybe
that would keep the light on?
What do you guy/gals think; oh yes, everything is tight and clean, but the ground from the engine to the body down there
looks a little beat up!

Try a 68 ohm 2 Watt - resistor on the D+ line- 12V exciter line and see if that works, on mine it does.

Thanks, will try that; any good place to find that resistor?
thanks,

is the light just barely glowing or is it full bright? also is it on with the key off?

There is one other item, get rid of the two piece pulley on the alternator and get a solid pulley with a slightly smaller diameter, this will kick up the voltage and amperage faster,, My two piece pulley broke and and I had a smaller solid pulley from a defective alternator I have kept around, same case size, I installed it and the light turns off instantly, before slightly slower--had to rev to shut it off -- no more on my 80 amp Alternator....
