The 3-phase charging system of brands for the Harley Davidson Fl Shovel models from 1981 to 1984 is characterized by its high efficiency and robustness. With an output of 25 amps in idle and 40 amps at speeds over 2,800 rpm, this system ensures reliable power supply. The combination of a narrow rotor and stator enables easy integration into the existing primary housing and voltage regulator bores without modifications on the motorcycle frame. The carefully balanced rotor is ventilated to enable optimal cooling of the stator, which ensures performance even under high load. An additional flange sealing spacer enhances the stability of the rotor, while the voltage controller is constant to 14.25 volts from idle to the maximum speed.
