Check battery terminals and clamps. Clean or
replace if necessary. Check that the starter cable is
secure at its terminals.
The ground strap, which connects the battery
negative (-) terminal to the engine, should also be
checked for corrosion or looseness.

sound is heard, check that the blue wire at the starter
is secure. If still no clicking sound is heard, the
starting (ignition) switch or the wire is defective.
Starter motor defective.
If the above checks have been performed, and no
