Dead Alternator Help Options

[dmenche914]

I have 914, Buick V6 powered. I have gone thru three alternators, and two or three regulators in a very short time, and wonder if anyone has a clue as to what might be happening.

The alternators, and regulators (914 parts) all have come from a known good stash of parts. The charging works fine for a short while, but after maybe a couple hundered miles of use, the charging stops, I get the red light on the dash, and the battery goes weak.

I was thinking at first maybe the lack of blower air to cool the alternator might be the problem, so last alternator had a fan / pulley put on it but now this one has died, that make three dead alternators. The alternator is not being over rev'd, as the drive pulley is actually smaller than on the 914 (driven pulley is stock sized)

All wires appear correct, and the battery is a good one, no shorts, and takes a charge fine when connected to my home charger.

Any possible explinations out there?

I'd like to try getting away from the 914 alternator system at this point (unless I am missing something) so do any conversion motor car owners have suggestions?

i do not think I want to waste a fourth 914 alternator on this unless i can figure out what is happening.


Anyway, hope someone can shed some light on my problem here.

thanks dave
