Loose or corroded battery cable terminals.

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 body to the

rear of the engine, should also be checked for

corrosion or looseness.

ignition terminal on starter.

The circuit is closed if a clicking sound is heard

from the starter when it is engaged. If no clicking

sound is heard, check that the blue wire at the starter

is secure. If still no clicking sound is heard, the

ignition switch or the wire is defective.

If the above checks have been performed, and no

fault is evident, the starter may be defective.

dim when the starter is engaged.
