thatdirtykid Posted November 8, 2011 Share Posted November 8, 2011 Is the voltage regulator in the alternator on a 1985 GL? I don't have a FSM just chiltons and the john muir idiot book. Neither are clear about where the voltage regulator is in this model. Thanks, I hate electrical work. Good thing this car is pretty simple electrics (so far, I haven't jumped in too far) Quote Link to comment Share on other sites More sharing options...

thatdirtykid Posted November 8, 2011 Author Share Posted November 8, 2011 Thanks, if i had the car with me I am sure i could have figured it out, but the car left the wife (and baby) stranded last night and we don't have another ride for me to drive out there.

Cougar Posted November 8, 2011 Share Posted November 8, 2011 (edited) If you think there is a alternator problem make sure the battery warning light works when you turn on the ignition. Power is supplied to the field windings through that lamp. Charging voltage should be between 13.2 and 14.8 volts with a good regulator. Bad output diodes can cause excessive AC ripple voltage. If there is more than .1 volt AC across the battery while the engine is running then there are some bad diodes inside the alternator.

man on the moon Posted November 9, 2011 Share Posted November 9, 2011 I have a spare alternator if you want one in the next few days. I'm in Denver. It's from a parts car I had a while back and no longer have. The alt is from a Loyale, but I think the two are close enough for government work.
