Motor
Only operate the starter switch (the engine cannot start) until the speed and
the current consumption of the starter motor can be measured.
ANNOTATION
THE SPEED VALUE STATED IS THE VALUE DISPLAYED BY THE DIAGNOSTIC TEST EQUIPMENT. THE ACTUAL
RPM IS NOT RECORDED, BUT THE VALUE IS VALID FOR THE CHECKS.
Special tool
020922Y Diagnose-Instrument
Electrical information
Current consumption at driving speed:
80 ÷ 120 A
Speed =
~ 300 ÷ 400 U/Min
YES point 6 NO point 7 NO point 8 NO point 9
5 - Reconnect the connections.
6 - The values are OK.
As a final confirmation, check the current consumption without load.
Remove the starter motor (see Alternator and Starter System chapter).
Reconnect ground and plus and check.
Electrical information
Current consumption without load:
<40 A
YES point 10 NO point 11
7 - Low driving speed
High current consumption
Check the engine rotation (example: damage to the crankshaft bearing), if no errors are found,
the starter motor needs to be replaced.
8 - Low driving speed
Low power consumption
Repeat the check, bridging or, better yet, replacing the connections on the remote relay
schen.
Check the new values.
YES point 12 NO point 13
9 - High driving speed
Low power consumption
The engine turns too easily, check the pressure at the end of compression.
If the values differ, proceed as indicated.
10 - The starter motor is OK.
11 - Check the armature rotation.
AGAINST - 166
