    Rated 5 out of 5 by from Great product on 60's GM So far so good holding 14v purchased this for my 1963 Impala, had issues with my previous alt and sound system would dim lights and had my voltage meter bouncing and not it a nice steady flow. I really like this alternator gave me the option to keep my dummy "gen" light on my dashboard. Purchased a pigtail and wired that way. Also upgraded my power and ground wires to 4 gauge some recommend 2 or 0.

    Rated 5 out of 5 by from Alternator for an 76 C10 I really want to say thank you for the service. I had receive my powermaster alternator, installed it and it did not work. I sent it back for a replacement and with questions, a new one was sent to me, with better stats then the first one. installed it an it work just as described. With the new electric parts added to my truck, the OEM parts just was not going to keep. Now with the 150 amps I don’t worry about my truck not starting on a rainy day. Again thanks for the quality service.

    Rated 5 out of 5 by from works well I purchased this on the recommendation of M.A.D. for the clean sign wave output. I wanted the 3 wire so as to not lose my horn relay, buzzer and volt gauge using the kit purchased from M.A.D. products.This alternator is smooth and quite and has a short and smooth recharge time.Really like it

    Rated 5 out of 5 by from Great alternator! Very easy to install. No more problems with dim headlights on my 68 Camaro due to the multiple amps in the sound system.

    Rated 5 out of 5 by from Works very well - fixed my electrical issues The old stock externally regulated alternator on my 66 Chevy II was not keeping up with it's battery maintenance job. I have added dual electric fans, electric fuel pump, etc. This alternator and 6 gage wire did the trick - I have not had a meltdown at the drag strip since the installation.

    Rated 4 out of 5 by from 150A Alternator I bought this new alternator for my 442. The alternator arrived and it had a rough spot and did not spin freely. I called Powermaster and they told me it is OK to run it. It is currently working, I'll keep you posted if anything changes. My old alternator was struggling to run the electric fans and fuel pump. The lights were pretty dim and my alternator belt would squeal when you opened it up. The belt squeal is gone and I have my lights back for now. I know there is something wrong inside this alternator, we will see how long it lasts. Luckily it is easy to replace.

    Will the standard wiring connector work with this? I have an all new wire harness in my 73 camaro, dont want or need single wire hook up. Do not want to cut or splice either, just need high output.

    Asked by: Koepperknot
    If you are replace a 12si style alternator then this will plug into your factory wiring harness.
