Alternator, Powermaster, 1954-88 GM, CS130, 105A, 1v Pulley, Chrome Baffle/Cone

GM CS130 105-Amp Alternator (V-Belt, Baffle/Cone) by Powermaster®

85-amp idle output, a compact case and two cooling fans support low-speed charging.

This Powermaster® CS130 provides 85 amps at idle and 105 amps at top end, supporting charging and accessory loads at low engine speeds. Its compact 5.12-inch case and 6.61-inch straight mounting span offer a smaller-case option for compatible 10SI/12SI installations; pulley alignment and wiring still need to match. Internal and external fans move cooling air through the alternator to dissipate heat. An internal regulator supports one-wire installation or a compatible OE-style hookup without a separate external regulator. The single-groove V-belt pulley is included. The front baffle and cone cover the pulley area for a finished engine-compartment appearance. Each alternator is individually dyno-tested to document output.
