1. INSPECT STARTER ASSEMBLY
  • ПРЕДОСТЕРЕЖЕНИЕ:
  • As a large electric current passes through the cable during this inspection, a thick cable must be used. If not, the cable may became hot and cause injury.
  • ПРИМЕЧАНИЕ:
  • The following tests must each be performed within 3 to 5 seconds to prevent the coil from burning out.

Mount the starter in a vise between aluminum plates.

Perform a pull-in test.

Remove the nut, and then disconnect the lead wire from terminal C.
