Stator Check - PIAGGIO MSS X9 EVOLUTION 250 Workshop Manual

Electrical system
High voltage coil voltage value
High voltage coil voltage value: > 100 Volt

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.
- Using a tester, check the continuity between con-
nection 4-3, 4-1 and 3-1.
- Check the earth insulation on the three stator
phases 4-earth, 3-earth and 1-earth.
Indicative resistance of each phase: 0.7 ÷ 0.9 Ω
Pick-Up Check
- Check that there is a resistance of about 105 ÷
124 Ω at 20°C between connection 2 and earth.
- If you read values other those stated, replace the
defective parts.
