Beverly Tourer 300 i.e.
Check the presence of fixed voltage between the
grey/black cable of the remote control base and
earth. If there is none check the continuity of the
grey/black cable between the fuse box (No. 4 10
A) and the remote control base.
N.B.
CONTINUITY TESTS MUST BE CARRIED OUT WITH THE
COMPONENTS DISCONNECTED. (SOLENOIDS, CON-
TROL UNIT, FUSES ETC.).
After switching to «ON», check that there is battery
voltage, for about 2 seconds, between the Black-
Green cable of the pump connector and the
ground lead with the pump connector disconnec-
ted. Otherwise, check the continuity of the Black-
Green cable between the pump connector and the
solenoid base.
Check the efficiency of the ground line of the fuel
pump by measuring the continuity between the
pump connector black cable, system side, and the
ground.
If, when switching to «ON», the pump continues to
turn after 2 seconds of activation, check, with the
control unit disconnected and the injection load
solenoid disconnected, that the Black-Purple ca-
ble (pin 20 on the interface wiring) is insulated from
the ground.
