11 Electric fan remote control
When switched to "ON", the fuel pump starts to rotate for 2 seconds and then stops. With engine on
and when a revolution timing signal is displayed, the pump is continuously supplied.
ELECTRICAL DATA
•
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 20A main fuse No. 2 and the injection load 15A No. 4 fuse are in good conditions.
Check the efficiency of the injection load remote
control: Check the resistance of the energising coil
between pins 86 and 85: 80 ÷ 120 Ohm.
Apply a voltage of 12V to pins 86 and 85; make
sure that there is continuity between pins 30 and
87 of the remote control.
Check the power supply line of the injection load remote control energising coil: after switching the line
"ON", make sure there is battery voltage for two seconds between the Green-Brown cable and the Blue-
Red cable of the remote control base. If there is none, check the continuity of the Green-Red cable
between the fuse box in the battery compartment and the remote control base and of the Red-Blue
cable between pin 20 of the control unit and the remote control base.
NOTE
CONTINUITY TESTS MUST BE CARRIED OUT WITH THE COMPONENTS DISCONNECTED.
(BATTERY, REMOTE CONTROLS, CONTROL UNIT, FUSES, ETC.).
Check there is fixed voltage between the Green-Red cable of the remote control base and the earth
connection. If there is none, check the continuity of the Green-Red cable between the fuse box (No. 4
15A) and the remote control base.
NOTE
CONTINUITY TESTS MUST BE CARRIED OUT WITH THE COMPONENTS DISCONNECTED.
(BATTERY, REMOTE CONTROLS, CONTROL UNIT, FUSES, ETC.).
