Undercharged Or Overcharged Battery Test

  1. If battery is undercharged or overcharged, disconnect generator wiring harness connector from generator. Turn ignition on, with engine off.
  2. Connect voltmeter from ground to terminal "L" and, if used, terminal "I" or "IG" in wiring harness. See Figure. If voltmeter reads zero volts, check for an open in circuit between terminal "L" and battery. Repair as required. Reconnect generator wiring harness connector.
  3. Start and operate engine at moderate speed with accessories off. Using a voltmeter, measure voltage across battery posts. If voltage reads greater than 16 volts, repair or replace generator.
