System Check

NOTE: Before testing, ensure generator wire harness connections are secure, drive belt tension is okay and battery is fully charged. After starting engine, wait at least 30 seconds before measuring voltage. Terminals "S", "L", "B", and "E" are marked on generator's rear cover. Terminal "F" is inside generator.
  1. Turn ignition on. If charge indicator light on instrument panel comes on, go to next step. If light is off, disconnect generator connector (terminals "L" and "S"). Ground terminal "L". See WIRING DIAGRAMS . If indicator light comes on, replace IC regulator. If light remains off, replace indicator bulb, reconnect generator connector and recheck.
  2. Start and run engine at idle. If light goes out, system is okay at this time. If light flickers or remains on bright, go to next step.
  3. Ensure belt is tight and wiring connections at rear of generator are okay. Run engine at 1500 RPM and measure voltage at generator terminal "B". If more than 15.5 volts are present, replace regulator. If less than 12 volts are present, field circuit is open, repair or replace generator.
