Load Test

  1. Attach tachometer to engine. Start engine. Load alternator by switching heater/air conditioner blower motor to high position and headlights to high beam. Increase engine speed to 2000 RPM.
  2. Voltmeter should indicate at least 0.5 volt more than battery voltage. If voltage reading is within specification, alternator operation is normal. If voltage reading is less than 0.5 volt more than battery voltage, proceed to REGULATOR "A" AND "I" CIRCUIT TEST.
