Voltage Regulator/Rectifier - PIAGGIO 633823 Service Station Manual

Electrical system
4) Check that there is insulation between the each
yellow cable and the ground.
5) If values are incorrect, replace the stator.
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 position OFF, connect the terminals of the tester between the negative pole
(-) of the battery and the black cable and only then disconnect the black cable from the negative pole
(-) of the battery.
4) With ignition key still at OFF, the reading detected by the ammeter must be ≤ 0.5 mA.
Check the charging current
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 tester terminals between the battery
terminals..
3) Turn on the engine, increase the revs 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.
- Start the engine and rev it up to a high engine speed while reading the value on the pincer.
With an efficient battery a value must be detected: > 20A
