Ignition coils (marelli bae 800 ak)

IGNITION COILS (MARELLI BAE 800 AK)

The ignition system has two twin outlet coils connected directly to the spark plugs for cylinders 1-4 and 2-3.

These coils are operated by the power modules located in the control unit.

A - B Connection to terminals 19 and 1 of the control unit.

C1... C4 To the spark plugs (as indicated by the numbers on the ignition coil frame).

D Supply: from the power relay (with the ignition switch in the ON position).

Recovery

Short circuit to +Vb error: immediate disabling of the injector operation for the defective coil.

Short circuit to earth or open circuit error: the control unit applies the charging time from the coil in open-loop.

PETROL VAPOUR CUT OUT SOLENOID VALVE

This is the normally closed closed type with a resistance of between 17.5 and 23.5 ohm at 20°C.

Depending on the duty-cycle supply, the capacity should be:

• A) duty-cycle 100% = 58 - 75 l/min
• B) duty-cycle 50% = 24 - 36 l/min
• C) duty-cycle 20% = 5.5 - 13.5 l/min.

Wiring connector

The numbers indicate the respective control unit pins.

Recovery: If there is a fault the operation of the solenoid valve is disabled.
