Explanation:
Diodes:
  • A diode is an electronic component that allows the flow of current in one direction only.
  • It exhibits low resistance in one direction and very high resistance in the opposite direction.
  • The diodes are made of silicon and these allow current to flow in one direction only.
  • They are so connected as to allow the current to flow from the alternator to the battery but not in the opposite direction.
  • Three diodes on the negative side are connected to the rear end housing and three diodes on the positive side are mounted on an insulated heat sink.
  • The diodes convert the AC produced by the alternator to DC since the automobile accessories are designed to utilize DC current.
