GENERAL SPECIFICATIONS

The charging system consists of the following

  1. Generator
  2. Charging system warning indicator
  3. Necessary wiring and cables

The charging system is a negative ground system. The generator (including an internal voltage regulator) is belt-driven by the engine accessory drive system. When the engine is started, the generator begins to generate AC, which is internally converted to DC. This current is then supplied to the vehicle electrical system through the output (B+) terminal of the generator.
