Voltage Regulator Check; Recharge System Voltage Check - PIAGGIO Beverly 300 i.e. Service Station Manual

Beverly 300 i.e.
Electric characteristic
Resistance:
0.2 - 1 Ω

Voltage regulator check

With a perfectly charged battery and lights off,
measure voltage at the battery poles with a high
running engine.
Voltage should not exceed 15 Volt.
In case higher voltages are detected, replace the
regulator.
In case of voltage values lower than 14 Volt, check
the stator and the corresponding cable harness.
Electric characteristic
Control voltage
14÷15 V to 1500÷12000 rpm

Recharge system voltage check

Look for any leakage
1) Access the battery by removing its cover under the saddle.
2) Check that the battery does not show signs of losing fluid before checking the output voltage.
3) Turn the ignition key to «OFF», connect the multimeter leads between the battery negative pole (-)
and the Black cable. Only then disconnect the Black cable from the battery negative pole (-).
4) With the ignition key always «OFF», the reading indicated by the ammeter must be must be ≤ 0.5
mA.
Charging current check
WARNING
BEFORE CARRYING OUT THE CHECK, MAKE SURE THAT THE BATTERY IS IN GOOD WORK-
ING ORDER.
1) Place the vehicle on its centre stand
2) With the battery correctly connected to the circuit, place the multimeter leads between the battery
terminals..
3) Turn on the engine, increase the engine rpm and, at the same time, measure the voltage.
Electric characteristic
Voltage ranging between 14.0 and 15.0V at 5000 rpm.
Maximum current output check.
- With the engine off and the panel at «ON» with the lights on, allow the battery voltage to stop at 12V.
- Connect ammeter pliers to the 2 recharge positive poles in output from the regulator.
