Powermaster 10si Style Alternators replace the stock 65 Amp alternator found on most GM vehicles from 1973-1986. It is also a good upgrade for the earlier Delco 10DN externally regulated alternators. This alternator can be operated as a 1-wire (needing only an output cable) or as a 3-wire (plug-in) for use with a dash light.
