KNOWLEDGE IS POWER

Your car's alternator converts mechanical energy to electrical energy in the form of alternating current.
The alternator consists of a rotor, a stator, a rectifier assembly, brushes, and a pulley.
An alternator problem can cause: a discharged battery, poor light operation, and erratic engine operation.

    Replaced my OEM alternator with this one. Drove the car to work. On the way home, battery showed discharge. Had it replaced with a mechanic close by. They told me it was only producing 10 volts.

    When I made the purchase, I was not informed that if the product was not available when I went to redeem the warranty, I would have to pay the difference for another one. I was only told that the warranty was for life.

    The OEM had another tab for another connection that is now not connected to anything. It has been working fine for about a month. Im using it for a Corrolla. Tip-rotate it 180 degrees horizontally first and it came out and in much easier.

    Needed a specific socket to loosen the belt, to remove old alternator. Still haven't received that. So I can't rate this one yet.

    The first one that I bought didn't work. So, I went to Auto Zone for replacement and they did replace the unit with ease. The is the good thing of having the warranty. The only hassle was to install and found out it is not working and to uninstall and install the replacement unit.

    It was a good by even though I had to replace it again but it was another thing that was bad that caused the new alternator to blow. It still met my expectations.
