Compu-Fire 3 Phase/40amp Charging Systems

High output 3 phase charging systems are standard on late model EFI H-D®’s. The Compu-Fire 40 AMP / 3 Phase charging systems can be used for replacement on EFI bikes or as an upgrade on carburetor models. Provides 25 amps of charging power at idle, and 40 amps continuously above 2800 RPM. The unique narrow rotor and stator combination fits Softail/Dyna primary cases and the voltage regulator bolts on without any frame modifications. The precision balanced vented rotor keeps the stator cooler in closed primary systems to maintain maximum output under all high current draw conditions. The large flanged seal spacer provides maximum support for the rotor and the voltage regulator output is calibrated to 14.25 volts from idle on up.
