This alternator is a direct replacement on 1968 to 1982 GMvehicles that had internal regulator alternators. This will also work on GM vehicles prior to 1968.


This unit hooks up exactly as the OEM unit does. For those wanting to use this alternator as a direct replacement on a GM vehicle, you will remove the black square plug in the side of the alt. case by hand, and your existing two wire harness will plug directly into the alt. You will also hook up the alt. cable that usually comes from the positive side of your battery to the back of the alt. The alt. cable is usually a 10 gauge wire that splits off from the large heavy positive battery cable.

For those wanting to use this on an early model car that had a conventional style alt. with an external firewall regulator, all you need to do is hook up the alt. battery cable to the back of the alt. No other wires need be hooked up. The voltage regulator is internal in this unit, and will operate with just this one wire hooked up to it. This is how you are able to eliminate the external voltage regulator as well as the mass of wires going to it on vehicles before 73. This unit actually fits in place of the early model external regulatoralts. GM did not change the physical size or design of the case when internal alts came in 1973.

The chrome finish on these alternator are very good, but may not be perfect.
