    47294 is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from U.S.A. built and tested I was very impressed with the packaging, instructions, and the obvious pride in the manufacture of this alternator. They also have an extensive product line covering a wide variety of applications.

    Rated 5 out of 5 by from NICE! I purchased this for my Ford F100. I was replacing a Tuff Stuff one wire so I was already setup for the GM style. I did have to make a spacer to make it work but it was a fraction of the price of the Ford style and looks and works great. You can't beat the price or delivery from Jegs either. I could not be more pleased with Powermaster and Jegs.

    Does Powermaster offer a warranty with this alternator?

    Asked by: WallyBGoode
    Powermaster warrants its products to be free from defects in material and workmanship for one year from the date of purchase. Products used for racing and car audio competition are only warranted up to the time of installation to be free from defects. No warranty exists after installation.
