Ignition system, ECU 950 Adventure
NOTE: this is a digital battery ignition system with the current supplied by the battery.
Battery voltage from the battery
1 flows to the ECU (control unit) 4 through the switched on ignition lock 2 and the switched
on emergency OFF switch
3.
The pulse generator
5 reports the crankshaft position to the ECU 4. The ECU uses this signal to calculate the ignition point for
each cylinder.
Battery voltage is supplied to both ignition coils
6 via the emergency OFF switch, the ground is switched by the ECU.
The coil on the fuel pump relay
7 obtains battery voltage from the ECU. After the ignition is switched on, the fuel pump relay
switches on for a few seconds and switches off again. If you start with the engine running, the fuel pump relay will stay on.
The fuel pump
8 obtains battery voltage from the battery through the switched on ignition lock 2 , via the fuse and the contact
on the fuel pump relay.
The throttle potentiometer (TPS)
9 reports the position of the carburetor throttle valves to the ECU via the yellow cable (on
connector AM or AR). The TPS is supplied with 5 volts of supply voltage (blue cable on connector AM or AR) by the ECU. The
black cable (on connector AM or AR) supplies the ground.
NOTE: See page 8-11 for the adjustment of the TPS.
The ECU receives a ground signal via the connected octane selector
bk (connector BA and BF) and uses the stored ignition curve
for fuel with a minimum octane number of 95 (ROZ 95). If the octane selector is disconnected (connectors BA and BF pulled
apart) the engine can be operated with fuel with a minimum quality of ROZ 80.
