The AC Delco 3 wire alternator was used in most General Motors products, and many types of heavy equipment, for a long time, which makes it readily available. This alternator has the advantages of high output, compact design and ease of use. With the proper brackets this alternator can be adapted to any vehicle or engine-powered equipment. Wiring this alternator is well within the capabilities of anyone with average mechanical skills.

Step 1

Disconnect the battery negative terminal.
