Engine 137, 275, 285 with ignition system ECI
It is not possible to test the ignition sparks for example during a roadside assistance on this ignition system.
It is only possible to determine faults in the ignition system through read out of diagnostic trouble code memory by means of STAR DIAGNOSIS.
The separation of electrical connectors at components of ignition system can only take place after switching off the ignition.
To avoid damage, the ignition must not be switched on without ground supply at power supply unit ECI (N91). A sufficient ground supply can only be assured, if the power supply unit ECI (N91) is bolted to the intake manifold (1).
