10SI 100 Amp Internally Regulated Alternators
    10SI Internally Regulated Alternator
  • 100 Amp
  • 1V Belt Pulley
  • Chrome

    Note: Charge Wire Not Included.

    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.

    Features:
  • Excellent Idle Output
  • 1 or 3-Wire Operation
  • Internally Regulated

    Note: Charge Wire Not Included.
