Battery Recharge Circuit; Stator Check - PIAGGIO 633929(IT) Service Station Manual

MP3 125
High voltage coil voltage value: > 100 Volt

Battery recharge circuit

The recharge system is provided with a three phase alternator with permanent flywheel.
The alternator is directly connected to the voltage regulator.
In turn, the latter is directly connected to earth and to the battery positive passing through the 15A safety
fuse.
The three- phase generator provides good recharge power and at low revs a good compromise is
achieved between generated power and idle stability.

Stator check

Disconnect the connector from the voltage regulator and check there is continuity between any yellow
cable and the other two cables.
Electric characteristic
Ohm value:
0.7 ÷ 0.9 Ohm
Also check that all yellow cables are insulated from
the ground connection.
If non-conforming values are detected, repeat the
checks directly to the stator. In case of further rep-
etitions of incorrect values replace the stator or
repair the wiring.
