Fault tracing starter motor and cabling General If the voltage level measured across the battery is less than 24.7V, the starter motor will not be able to crank the engine at normal speed.
Voltage measurement check 1.
Check that the voltage across the battery is at least 24.7V unloaded, by measuring across the battery terminals with multimeter 9510060.
2.
Turn on the main circuit breaker.
3.
check that the voltage between terminals 30 and 31 on the starter motor is the same as the battery’s.
Brushes The specification for the starter motor brushes is given below. Brush condition New = 23 mm Replace at = 13 mm
