    Been fighting burning up regulators and many other issues for 3 years on 91 w250. Was just fixing to sell the pickup when heard about this alternator an figured I'd give it a try. Not only does it charge great, it isn't boiling my battery, all my lights started working, speedometer works again and so do power steering and brakes. I know no relation there but im so happy I'll just go ahead and give credit to this fine alternator. Thanks a million.

  3. one wire alternator 5 Star Review

    I have a 12 valve swapped 2004 Dodge Ram 3500. The previous owner had a low power GM one wire in it that finally stopped working. I received this alternator and bolted it right up and it works flawlessly! I'd recommend this to anyone that has a cummins swap.

    The charging volts are higher than I would like, wished it had a adjustable charging volts.
