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).
- Connect an ammeter as described in NO-LOAD TEST step 1). Start engine. Turn on high beam headlights and place heater control on HI.
- 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.
