Comments about CARQUEST Alternator - Remanufactured - 140 Amps:
I used the 20% discount by ordering online and got a Great price....better than any local competitors.
I'm not a mechanic, and for me it was really easy to remove the old one and install the new one. It took me less than 40 minutes total.
Haven't owned it long enough to rate the performance and life but so far I'm a happy camper.

Q:wHAT ARE THE THREE PRONG POST LOCATED ON THE BACK OF THIS ALTERNATOR FOR?
A:The function of 3 prong plug is to control the alternator on when to apply voltage to the field windings. When the field windings are energized and spinning, then the stator will generate power. By changing the strength of the field (spinning portion) of the alternator, you vary the output from the stator windings. Without the regulator and field windings energized, there is no charging.
A:The FOUR pin connector off the side is for controlling the alternator's regulator. The large THREE pin plug next to the battery terminal connect to the stator and provide three phase AC current for a heated windshield option. GM decided to save the rectifier assembly some wear and tear by doing so, since a heating coil does not care what kind of current it uses. You should cover these connections if you do not use them to prevent a shock or shorting hazard. Or order an alternator without this option installed.
