ENGINE 137.970




N91 ECI ignition system mains unit
Connector assignment:
Pin 4, 5 Voltage supply, circuit (terminal) 87
Pin 7 Auxiliary voltage approx. 23 V for right ignition module
Pin 8 Auxiliary voltage approx. 23 V for left ignition module
Pin 9 Voltage approx. 180 V for right ignition module
Pin 11 Ground for right ignition module
Pin 12 Battery voltage for right ignition module
Pin 13 Battery voltage for left ignition module
Pin 14 Ground for left ignition module
Pin 16 Voltage approx. 180 V for left ignition module

Danger! Risk of fatal injury when touching parts conducting high voltage when the ignition is switched off.
After ignition is turned OFF, only disconnect the plug on the ECI power pack after waiting 3 minutes.

The power pack generates the following different DC voltage for each ignition module from the battery voltage:
- 23 volts as an auxiliary voltage for ion current measurement
- about 180 volts for generating the ignition voltage
Terminal 87 is also looped to each ignition module.
