Stator check
- Using a tester, check the resistance between the
stator wiring.
N.B.
VALUES ARE STATED AT AMBIENT TEMPERATURE. A
CHECK WITH THE STATOR AT OPERATING TEMPERA-
TURE LEADS TO VALUES HIGHER THAN THOSE STATED.

Voltage regulator check
Voltage regulator
A fault in the voltage regulator can cause the fol-
lowing problems depending on the type of fault:
1) Blow out of the lighting system bulbs.
2) Failure of the lighting system.
3) Excessive battery charging (blowing of main
fuse).
4) Battery recharging failure.
5) Failure of the turn indicators.
6) Failure of the oil and petrol check lamp.
Operations
FAULT 1
:
Make sure that at 5000 rpm with the lights on that
the regulation voltage is between 13V and 14.5V.
Make sure that at 5000 rpm with the lights off the
regulation voltage is ï£ 16V.
If the regulation voltage is greater than >16V re-
place the regulator.
