Charging Rate
The alternator output is controlled and changed to direct current by the voltage regulator.
It is possible to overload the vehicle's charging system by adding too many electrical accessories. If the combined electrical accessories operating at any one time consume more electrical current than the vehicle's charging system can produce, the electrical consumption can discharge the battery and cause damage to the vehicle's electrical system.

  • This unit requires no interval attention. If any electrical system trouble is experienced that might be traceable to the alternator or voltage regulator, the motorcycle should be taken to a Harley-Davidson dealer who has the necessary electrical testing equipment to give the required attention.
  • For model specific information regarding the voltage regulator, refer to the appropriate Service Manual or see a Harley-Davidson dealer.
