Load Test

  1. Start engine and turn headlights on high beam and heater control on "HI". Run engine at 2000 RPM and check amperage. On Celica, Corona, Land Cruiser and Tercel models, ammeter should read more than 30 amps.
  2. On Toyota Pickup and Starlet models, reading should be more than 20 amps. If reading is less, repair alternator.
    NOTE: If reading is low due to a fully charged battery, it may be necessary to crank engine with coil disconnected for about 15 seconds to discharge battery.
