Load test (inspect charging circuit with load)
|
In the load test, when an electrical load is applied, the alternator output is checked by measuring the output current according to the applied load.
The important point in this test is applying as heavy a load as possible. If the electrical load is insufficient, even if the alternator operation is normal, the output may not exceed 30A (specified value when the engine speed is at 2,000 rpm).
Therefore, if the output current does not meet the 30A specified value, it will be necessary to increase the electrical load and perform the inspection again. If the measurement result is less than the specified value, the alternator can be judged as faulty and the malfunction is probably in the components of the alternator that have a generating or rectifying function. |
HINT:
Even when the measurement result exceeds 30A, the maximum rated power is not always output. The maximum rated power can be determined by measuring the output current limit, while maintaining a constant voltage with the engine speed at approximately 2,000 RPM, and progressively increasing the electric load.
