dealer.

Condition: Starter fails to operate (or operates very slowly)

Possible cause Correction

Weak battery or dead cell.

With the starting (ignition) switch in the "Driving"

or "On" position, check to see if the warning lights

on the dashboard come on and if they stay on when

the starter is engaged. If the lights do not come on or

if they go off when the starter is engaged, the battery

is discharged or see below.

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 battery

negative (-) terminal to the engine, should also be

checked for corrosion or looseness.

Open circuit between starting (ignition) switch

and starting (ignition) switch 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

starting (ignition) switch or the wire is defective.

Starter motor defective.

If the above checks have been performed, and no

fault is evident, the starter may be defective. NOTE:

In this case the headlight intensity will not dim when

the starter is engaged.
