Starter motor check

If a fault has been diagnosed in the starter motor, it is necessary to proceed as
follows with the check:
Connect a tester between earth and the starter motor terminal.
Check that there is continuity between the positive pole and the engine earth.
If there is no continuity, substitute the starter motor. Apply a small quantity of
LOCTITE 243 to the bolts of the starter motor.
