Volvo 1990 240 Model
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.
