"Fit a fresh drive belt and set the tension with the alternator, and clean the battery and ground connections - a bad ground fakes a charging fault."
Frequently Asked Questions
Is this new or remanufactured?
It is a remanufactured alternator. Confirm your original style against the listing photos before ordering.
Should I replace the belt too?
Fit or set a fresh belt with the alternator so charging is reliable.
How do I test the alternator?
With the engine running, measure battery voltage; roughly 13.5 to 14.5 volts means it is charging. Below that, or a battery that keeps dying with clean connections, points to the alternator.
