Load Test

NOTE: During load test procedure, if voltage reading is low due to a fully charged battery, disable ignition system and crank engine for about 15 seconds to partially discharge battery (if necessary).
  1. Connect an ammeter as described in NO-LOAD TEST step 1). Start engine. Turn on high beam headlights and place heater control on HI.
  2. Increase engine speed to 2000 RPM and check ammeter reading. Ammeter should read more than 30 amps. If amperage is less than specified, repair or replace alternator.
