Stator Check - VESPA GT 125 Workshop Manual

Electrical system
The three- phase generator provides good recharge power and at low revs a good compromise is
achieved between generated power and idle stability.
For this reason, it is very important that the idle speed is adjusted as prescribed.

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.
