7- Low trailing speed
High electrical absorption
Carry out a test of the engine rotation (example: possible melting of the bushes) and if no anomalies
are found, replace the starter motor.
8- Low trailing speed
Low electrical absorption
Repeat the test, bridging the power terminals of the starter remote control switch or even better replacing
them.
Check the new values.
YES go to 12 NO go to 13
9 - High trailing speed
Low electrical absorption
The engine turns too freely, check the compression end pressure.
If the values are not correct proceed as follows.
10 - The starter motor works properly.
11 - Check the rotation of the armature.
12 - Replace the starter remote control switch.
