PIAGGIO Beverly 500 i.e. - Pump Consumption Check; Fuel Filter Check

Pump consumption check
The pump power consumption may vary according
to:
- Power supply voltage
- Pump running-in
- Regulation pressure
- Delivery filter cleaning
To check the current consumption, proceed as fol-
lows
- Disconnect the pump remote control switch con-
nector.
- With key switch set to "OFF", connect the jump-
ers 30-87 on the connector using the tester probes
in ammeter function (see figure).
- Check the pump rotation and power consumption
N.B.
THIS CONSUMPTION REFERS TO:
- POWER SUPPLY VOLTAGE = approx. 12 V
- PUMP RUN IN
- SYSTEM PRESSURE = 300 kPa (3 BAR)
- FUEL FILTER CLEAN
Electric characteristic
Current consumption:
approx. 3.5 - 4.2 A
A dirty filter causes an increase of input. If the pressure-relief valve opens, the pump absorbs approx.
6-7A.
In case of excessive input (5A), replace the filter. See pump support overhaul.
If the fault continues, replace the pump.
Fuel filter check
To check the fuel filter inspect the following:
- Free flow
- Current consumed by the pump. A clogged filter causes:
- Poor performance especially at full power
- Pump input increase
N.B.
DO NOT BLOW THE FILTER WITH COMPRESSED AIR. A DAMAGED FILTER MAY CAUSE THE
INJECTOR CLOGGING.
