1992 Volvo 240
pg. 104 Service diagnosis
The diagnoses outlined below are intended to serve only as a guide to locate and temporarily correct minor faults. Causes of unsatisfactory performance should be investigated and corrected by your Volvo dealer.
Condition: Starter fails to operate (or operates very slowly)
Possible cause
Weak battery or dead cell.
Loose or corroded battery cable terminals.
Open circuit between starting (ignition) switch and starting (ignition) switch terminal on starter.
Starter motor defective.
Correction
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.
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.
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.
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.
