I do need to replace the serpentine belt (that's on my "to-do" list), but the other pulleys are all new - or are very low mileage.[/b]
Measure the battery voltage at 2000 RPM
or so. It should be 14.5 or better with the car reved up.
If not, you may have a control issue with the alternator. The control wire that tells the alternator to turn on
could either have a bad connector, or other wiring issues.
Which wire would that be?
Also, would an accidental short of the alternator with a bracket (by way of a prybar touching the hot wire and said bracket at the same time) cause it?
I wouldn't think so, but I want to touch all bases. I really don't want to give up on this car, seeing as how it has a lot of life left in it.
Here is the back of a typical 3G alt.
look at the little single terminal between the big lug with the heavy wire, and the multipin plug.
this should be a single wire. get a volt meter and read what this pin reads on the volts scale with
the motor running. While you at it, measure the battery voltage with the motor at idle and
at 2000 RPM
here is what the two plugs look like:
