Circuit Leak Test - PIAGGIO Beverly 300 i.e. Service Station Manual

Beverly 300 i.e.
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
relay 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 re-
lay disconnected, that the Black-Purple cable (pin
20 on the interface wiring) is insulated from the
ground.

Circuit leak test

Install the specific tool for checking the fuel pressure, with the pipe fitted with the gauge.
Check during regular operation by placing the ap-
propriate tool between the pump and the injector.
With the battery voltage> 12 V check that the fuel
pressure is 2.5 BAR and that the input current is
1.4 to 1.8 A
With the battery voltage > 12 V, check the capacity of the pump flow rate by disconnecting from the
injector the pipe equipped with the pressure gauge of the appropriate tool. Make a graded burette
available with a flowrate of approximately 1 L. Rotate the pump using the active diagnosis of the palm
