12. Restore the insulation or replace the wiring.
GO TO point 11
13. Connect the flywheel connector and repeat the
insulation checks from earth and from positive.
1 - 19 > 1MOhm
1 - 20 > 1 MOhm
YES point 15 NO point 14
14. Restore or replace the stator with phase - rpm
sensor.
GO TO point 17
15. Check the phase - rpm sensor resistance
19 - 20 = Ohm…… at 20°
(detected 106.7W)
YES point 17 NO point 16
N.B.
IF THE CHECK IS DONE WHEN THE ENGINE IS
HOT, RESISTIVE VALUES WILL BE HIGHER
16. When out of tolerance resistive values are de-
tected, replace the stator with phase - rpm sensor.
17. Measure the alternated voltage produced by
the phase - rpm sensor with engine driven by the
starter.
19 - 20 = 3.5 ¸ 4 V ~
(at 500 - 600 RPM)
YES point 19 NO point 18
