STARTER (for 2.7 kW Type) INSPECTION


  1. INSPECT STARTER

    CAUTION:

    As a large electric current passes through the cable during this inspection, a thick cable must be used. If not, the cable may become hot and cause injury.

    Note

    These tests must be performed within 3 to 5 seconds to prevent the coil from burning out.


    1. Mount the starter in a vise between aluminum plates.

    2. Perform a pull-in test.
