Injection
9. Fuel injector
10.Electric fan solenoid
When switched to "ON", the fuel pump starts to rotate for two seconds and then stops. When the engine
starts, in the presence of rpm timing signal the pump is continuously supplied.
•
Pump winding resistance ~ 1.5 Ohm
•
Input current during regular operation 1.4 - 1.8 A
•
Input current to the closed hydraulic circuit ~ 2 A (to be checked with appropriate tool for
fuel pressure control choking the circuit on the return pipe)
Check that the injection load 15A fuse No. 2 works
properly.
Check that the 7.5A fuse No. 5 for live control unit
power works properly.
Check the efficiency of the injection load solenoid.
Check the resistance of the energising coil be-
tween pins 86 and 85: 40 to 80 Ohm
Apply a voltage of 12V to pins 86 and 85; make
sure that there is continuity between pins 30 and
87 of the relay.
Check the power supply line of the injection load
solenoid energising coil: after switching to "ON",
make sure there is battery voltage, for two sec-
onds, between the Red-White cable and Black-
Purple cable of the solenoid control base. If there
is not, check the continuity of the Red-White cable
between the fuse box under the saddle hinge and
the remote control base and of the Black-Purple
cable between pin 22 of the control unit and the
remote control base.
