Current Output Test

CAUTION: This load test must be performed within 15 seconds to prevent damage to test equipment.
NOTE: On certain brands of test equipment, this load will be applied automatically. Refer to the operating instructions supplied with the test equipment.

This test will determine if the charging system can deliver its minimum test current (amperage) output. A volt/amp tester equipped with both a battery load control and an inductive type pickup clamp (ammeter probe) will be used for this test.

  1. Engage the parking brake, make sure the transaxle is in PARK (A/T) or NEUTRAL (M/T) and start the engine.
  2. Bring the engine speed up to 2500 RPM and hold.
  3. Slowly adjust the rheostat control (load) on the tester to obtain the highest amperage reading. Do not allow the voltage to drop below 12V.
  4. The ammeter reading must meet the minimum amps specifications listed on the specifications chart.
  5. Turn the load control knob on the tester to the "OFF" position but continue to hold the engine speed at 2500 RPM. If all circuitry is okay, the amperage should drop below 15 to 20 amps. This may take several minutes with all electrical accessories "OFF".
  6. Remove the volt/amp tester. If the minimum amperage requirements could not be met, test the generator. If the generator tests okay, check the charging system circuitry.
