- Left-hand rotation view from pinion side.
- Connected to the engine by pinion and crown wheel on crankshaft, transmission side.
- Push-button control.
- Battery used for the test:12V-3,6Ah.
N.B.
THESE VALUES MUST BE MEASURED WITH A CHARGED BATTERY AND AFTER THE STARTER
HAS BEEN ROTATING FOR 30" UNDER CONDITIONS OF POINT 1
Ignition circuit
All the control operations of the system that require
the disconnection of cables (checks of the con-
nections and the devices making up the ignition
circuit) must be done with the engine off: if this is
not done, the controls might be irretrievably dam-
aged.
Stator check
- Using a tester, check the resistance between the
brown-earth and black-earth terminal.
N.B.
VALUES ARE STATED AT AMBIENT TEMPERATURE. A
CHECK WITH THE STATOR AT OPERATING TEMPERA-
TURE LEADS TO VALUES HIGHER THAN THOSE STATED.
Electric characteristic
Stator : Brown-earth
~ 170
Ω
(Pick-Up)
Stator : Black-earth
~ 1

Voltage regulator check
A malfunction in the voltage regulator might cause the following problems depending on the type of
fault:
1) Bulbs burned out (regulator in short circuit).
2) Malfunction of the lighting system and the electric starter (regulator interrupted).
3) Battery not recharging.
4) Turn indicators not working.
