Alternator, Powermaster, 1986-87 GN/T-Type/Regal, CS144, 170Amp, 6 grv Pulley

1986-87 Buick Regal CS144 170-Amp Alternator (6-Rib) by Powermaster®

115-amp idle output supplies charging capacity at low speed; dual fans help dissipate heat.

This Powermaster® CS144 supplies 115 amps at idle and 170 amps at top end, adding charging capacity for vehicles whose electrical accessories exceed a lower-output alternator. Internal and external fans help dissipate heat. The large 5.90-inch case uses a 7.24-inch straight mounting span and includes a six-rib serpentine pulley. An internal regulator supports one-wire charging or a compatible OE-style hookup without a separate external regulator. Each alternator is individually dyno-tested. Confirm case clearance, belt alignment and charge-cable capacity for the increased output.
