Test procedure
– Connect multimeter between terminal 50 -2- (with connector
connected) and battery earth/engine earth to measure volt-
age.
– Operate ignition/starter switch, and check the voltage supply.
Specification: at least 8.0 V
If there is voltage on terminal 50 -2- on solenoid switch:
– Check voltage on coil connection -3- and battery earth/en-
gine earth.
– Operate ignition/starter switch, and check the voltage. Speci-
fication: at least 8.0 V
If specification is attained:
– Repair starter -B-.
If the specification is not attained:
– Renew solenoid switch.
If there is no voltage on terminal 50 -2- on solenoid switch:
– Check voltage on terminal 50 on ignition/starter switch and
battery earth/engine earth referring to current flow diagram
⇒ P age
486, current flow diagrams.
– Operate ignition/starter switch, and check the voltage. Speci-
fication: at least 8.0 V
If the specification is not attained:
– Renew ignition/starter switch -D-.
If specification is attained:
– Check wiring between Ignition/starter switch and starter for
open circuit referring to current flow diagram. Cable resist-
ance: max. 2.0 Ω.
1.3 Starter -B- turning too slowly and not
cranking engine properly
Test prerequisites
● Battery charged and tested.
● Poly V-belt tension OK and alternator secured properly
● All electrical consumers must be switched off.
● The connections on the solenoid switch/earth strap – be-
tween engine, power unit and battery – must be firmly seat-
ed and must not be corroded.
Test procedure
– Operate ignition/starter switch.
If starter does not crank engine properly:
– With ignition switched off, disconnect earth strap from bat-
tery.
