My alternator light stays on after I start the car. It was dim, and it would go off (and stay off) as soon as I got the RPMs up over 1000 or so. I did eventually find a faulty connection between the battery and the Voltage Regulator, which I thought would solve my problem. Instead, I now have a similar condition except that the charge light is on full bright (not just dim, like before) until I blip the rev's up a bit. It will still go off and then stay off for the rest of the time the car is running.
With the car running at about 1000rpm I am getting 14V at the battery. Pulling the VR and shorting D+ to Df results in 16-17V at the battery, so I am assuming my alternator is good.
I thought there was something going on with the VR not applying enough voltage to the field at start-up, so I ordered a replacement. They new Voltage Regulator is an AC/Delco part, not the OEM. I have exactly the same issue with the new Voltage Regulator.
Any ideas?
Thanks!
