Powermaster Alternator, GM Original Look, 12SI, 100 amps, 12V, 1-Wire / 3-Wire, Single V-Belt Pulley, Straight Mount, Aluminum Case, Chrome, GM, Each

Installed this alternator in conjunction with a new complete wiring harness and digital dash on my ‘71 Chevelle Malibu with A/C. Easy install and charges great. Looks good under the hood as well!

great quality! Looks amazing and performs perfectly in my setup.

I love the look and performance of my chrome Powermaster alternator. It has done me a good job for two years. I started getting a battery draw that would discharge the battery after a couple of days. I traced it to the alternator. I contacted Powermaster to see if I could get it repaired. They were excellent in their response to me and I sent the alternator to them. About 5 days later, I got a call from John in returns and he told me that he found several problems with my installation including loose belt and paint on the mounting pad which was preventing a good ground, but that I also had a bad diode. They replaced the diode pack and sent me some instructions for a more proper installation. The work was done at their cost and the alternator was back to me in record time. Cost me $80 including shipping. All told, it was 9 days from the time I shipped until I received the repaired alternator. Their service and attention to detail is second to none!

The box it came in was not insulated at all but good thing the power master box the product came in was well packaged. Just appeared it was thrown in a box and mailed. Power Master makes a great product and it works great.

Nice looking alternator. And gets the job done.

Missing Parts very very poor product from Amazon. Their ideals are much higher than this charles Not worthy of being called on Amazon product charles

I have bought many from Powermaster. Main thing is they are quality alrlternaters. Also the chrome is show quality. Worth the little bit more $ than the cheap junk.

Solid upgrade to my 10SI 61 amp. Wasn't able to get above 13 volts before and now I'm sitting at 13.9-4.1volts. Dual 16" electric fans, air bags, sound system with large touch screen, Sniper EFI with timing control, and digital meters.

Calidad de alternador lo instale en un Chevy 350 y supero mis espectativas

Nice chrome finish, single wire is a nice option to cleanup wiring in the engine bay. Been running it for a couple weeks and no issues so far.

Die Lichtmaschine ist top verarbeitet und von sehr guter Qualität. Ich konnte sie easy einbauen und anschließen. Sie arbeitet einwandfrei und bringt volle Leistung. Meine alte, defekte Lichtmaschine (gleicher Typ, über 15 Jahre alt) konnte sie super ersetzen.

Very nice product packed well and fit perfectly on sbc without mod 3 wire alternator

Sie passte nur ganz knapp in den Halter, aber sonst okay.
