Charging System Light: 3.0CL

  1. Perform PRELIMINARY INSPECTION . Turn ignition switch to ON position. If charging system light illuminates, go to step  4. If charging system light does not illuminate, go to next step.
  2. Disconnect generator 4-pin harness connector. Connect a fused jumper wire between ground and generator 4-pin harness connector terminal No. 3 (White/Blue wire). See Fig 1. Turn ignition switch to ON position. If charging system light illuminates, go to next step. If charging system light does not illuminate, check fuse No. 4 (7.5-amp) in underdash fuse/relay box. Replace fuse if necessary. If fuse is okay, check for faulty charging system light bulb. Replace if necessary. If bulb is okay, repair open in White/Blue wire. See WIRING DIAGRAMS .
  3. Using DVOM, measure voltage between ground and generator 4-pin harness connector terminal No. 1 (Black/Yellow wire). If battery voltage exists, replace generator. If battery voltage does not exist, repair open in Black/Yellow wire. See WIRING DIAGRAMS .
  4. Start engine. Charging system light should turn off. If charging system light remains on, go to next step. If charging system light turns off, go to step  6.
  5. Turn ignition switch to OFF position. Disconnect generator 4-pin harness connector. Turn ignition switch to ON position. If charging system light does not illuminate, replace generator. See GENERATOR  under REMOVAL & INSTALLATION. If charging system light illuminates, repair short to power in White/Blue wire.
  6. Using DVOM, measure voltage between ground and generator 4-pin harness connector terminal No. 1 (Black/Yellow wire). If battery voltage exists, replace generator. If battery voltage does not exist, repair open in Black/Yellow wire between generator and underdash fuse/relay box.
