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 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.
