After reading the good stuff on the clutch, I'll ask for ideas on this
problem. First history:
Previous owner installed a Postive Ground alternator ... from what I can
tell, it looks like a Motorola AP12X600 with a Delco Remy 9000590
regulator. He said he had trouble with it charging at times, but when I
got it last year, it was charging some ... about 13 volts on a full battery
... low I thought, but at least it wouldn't boil the water out of the
battery. Anyway, recently battery went flat (when he put on the
Alternator, they didn't wire in any amp meter, etc...so it was a "surprise"
.... by the way, the Amphi would run on 9 volts once jump started ... but
when it stayed at 9 volts it deemed more investigaion), so in investigating
over the weekend had these symptoms. Sometimes no charge, other times get
13.2 to 14 volts when rev engine, turn car off, do it again and sometimes
no charge, One "cycle" pegged voltmeter over 16 volts, another time it had
a constant swing 14 to 16 volts.. other times nothing .. nada ... 12.5
(fully charge battery) Take to car to alternator shop and verifies
nothing coming out ... he tests the alternator and when his machine applies
a field voltage, we get current out of the alternator. Assumption, bad
regulator. Get a new regulator (same type which says for either Positive
or Negative ground).... nada .... Check regulator connections, plug,
wire continuity ... all seem good. still nothing ... try old regulator ...
nothing. Check alternator again on machine ... puts out current when
field applied externally. Suggestions??? I'm about ready to wire in a
Generator/regulator from a parts car.
