TROUBLE SHOOTING
Note. See TROUBLE SHOOTING article in GENERAL INFORMATION.
ON-VEHICLE TESTING
The starter should be submitted to performance tests whenever it has been overhauled, to assure its satisfactory performance when installed on the engine. Three performance tests, no-load test, load test, and lock test, are presented here; however, if the load test and lock test cannot be performed, carry out at least the no-load test. For these performance tests. (Scheme 4)
NO-LOAD TEST
With switch ON, adjust the variable resistance to obtain 11 volts, take the ammeter reading, and then measure the starter speed. Compare the values.
LOAD TEST
Apply the specified braking torque to starter. The condition is satisfactory if the current draw and starter speed are within specifications.
LOCK TEST
With the starter stalled, or not rotating, measure the torque developed and current draw when voltage is adjusted to the specified voltage.

Inspection
Inspect for cracks and loose connections.
