Alternators, just like starter motors, come in many shapes, sizes and configurations. If matched up correctly, the alternator should work for you and charge your battery as intended. We’ve provided this guide to allow you to measure your current alternator so you can compare to the ones listed on our website. All our alternator listings come with a ‘specifications sheet’ so you can easily match up an alternator to the one in your vehicle.

Measuring the Alternator

There are a few key points that will differentiate alternators from each other. They are:
• Voltage and Output (Amps)
• Pulley Type and Diameter
• Regulator Type
• Mounting Positions and Sizes

The diagram below shows how to match up these details.
