Quick Tech: Tips for Choosing and Installing an Alternator

There are many factors to consider when purchasing an alternator.

Things like amperage, voltage, pulley ratio, and wiring all come into play. We’ve covered some of these topics in this earlier post; however, we still receive many questions about alternators from readers. So we teamed up with the tech experts at Summit Racing to get answers for some of the most common questions:

  • Why would I need to upgrade my alternator?
