Operation Manual

pump circuit 6
Check, on switching to "ON", that there is battery
voltage, for about two seconds, to the Black-Green
cable of the pump connector and earth with pump
connector disconnected. Otherwise check the
continuity of the Black-Grey cable between the
pump connector and the base of the remote con-
trol.
Check the efficiency of the earth line of the fuel
pump by measuring the continuity between the
pump connector black cable, system side, and the
earth.
If, when switching to "ON", the pump continues to
turn after two seconds of activation, check, with the
control unit disconnected and the injection load re-
mote control disconnected, that the Black-Purple
cable (pin 20 on the interface wiring) is insulated
from the earth.
