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!

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.

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

The alternator worked great on my 66 Pontiac. The chrome finish is beautiful and definitely brings up the overall look under the hood.

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.

Easy install and perfect fit for my ‘67 Camaro. Looks great and matches my other chrome/polished parts.

I thought the Chrome was really nice way better than I thought it would be. Bolted right up to my aftermarket brackets it came with nice directions if you wanted to hook it up one wire or pull the rubber plug out and plug in the factory plug it's still going to be a little while before I put the motor in my vehicle I'm sure it's going to work fine after reading all the reviews comes with a little certificate telling you how much it put out at different RPMs.

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.

Pour ma voiture ancienne et je suis très satisfait merci beaucoup.

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.

Se mira de muy buena calidad en cromo y en material, acabado perfecto,solo falta ponerlo a mi Montecarlo en envío solo duró 5 días para llegar Guadalajara lo recomiendo al 100%.

Alternateur costaud très bonne puissance

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