Rotor, 22 & 32 AMP

PERFORMANCE ALTERNATOR ROTOR FOR 22 AND 32 AMP BIG TWIN - V-Factor

This alternator rotor features a fully encased set of magnets that have no way of working loose like the OEM rotor is known to do. Instead of having just six long magnets like the OEM rotor, this rotor has 12 short magnets to match the number of laminated windings found on the stator. The steel housing is fully machined for perfect concentricity and the inner and outer washer is integrated into the housing with a full complement spline. this type of washer/housing configuration produces a spline with a .075" thick inside integrated washer and a .220" thick outside integrated washer with an overall width of .470" as opposed to the less than adequate OEM thickness of .187". Not only is this rotor a sensible replacement part for stock size motors, it is almost a mandatory item for high performance motors. Fits Big Twin models 1981/1997 with a 22 amp or a 32 amp charging system. Will not fit EFI models.

STATOR MOUNTING HARDWARE FOR BIG TWIN 1970/LATER

Don't be sorry, be sure when replacing the stator with this Stator Mounting Hardware Kit and Backing Plates. If an ounce of prevention is worth a pound of cure, then it would be wise to replace the mounting hardware when replacing the stator. No one wants to do the same job twice and imagine the damage should the old hardware loosen and back off into the alternator!

VOLTAGE REGULATOR/RECTIFIERS FOR BIG TWIN - Compu-Fire

Designed to reduce unnecessary drag on the engine, these regulator/rectifiers are of the "series" type that actually unloads the stator whenever the battery reaches full charge. The OEM "shunt" style grounds the system at full charge, creating a continuous drag on the engine. The chrome plated die cast housing measures a mere .750" thick (except 16206) and all of the electronics are fully potted so vibration and the elements cannot affect its performance. Instructions included. Made in the U.S.A.

12-VOLT GENERATOR WITH BUILT-IN REGULATOR FOR ALL MODELS - Cycle Electric Inc.

Integrated design combines the solid state regulator into the end of the generator for an uncluttered look with simplified wiring.
The regulator incorporates the armature support bearing to keep the overall length (7.58" from gasket surface fins) to a minimum.
The regulator not only controls voltage, it limits current (amps) in an inverse proportion by sensing the temperature of the armature. As the temperature increases, the amperage decreases. This provides more amps after a cold start to recharge the battery faster (5 minutes instead of 20) yet protects against overheating.
Instruction are included. 2 Year Limited Warranty. Made in the U.S.A.
