FAULT 4
a) Interposing the AC tester between the black and
yellow cables on the regulator, check the genera-
tor output voltage is within the prescribed values
(this measurement must be carried out with the
battery detached). In the event of anomalies, re-
place the stator; otherwise proceed to point b).
b) Insert an ammeter between the stator (blue ca-
ble) and the battery and check with the tester that
the current output, at 3,000 rpm and with the bat-
tery kept between 12 and 13V, is as shown. If the
values thus obtained are lower than prescribed,
proceed by replacing the regulator.
N.B.
BEFORE CARRYING OUT THE CHECKS ON
THE REGULATOR AND RELATIVE SYSTEM, IT
IS ALWAYS GOOD PRACTICE TO CHECK
THAT THERE IS CONTINUITY BETWEEN THE
BLACK CABLE AND THE GROUND.
N.B.
TO KEEP THE BATTERY BETWEEN 12 AND
13V, CAUSING CURRENT ABSORPTION BY
THE SYSTEM, A 12V - 35W BULB CONNECTED
BETWEEN THE + BATTERY AND GROUND
CAN BE USED.

In the event that the turn signal lights are not op-
erational, proceed as follows:
•
Remove the regulator connector and
insert the tester terminals between pin
5 and ground.
•
Turn the ignition switch onto ON and
check for battery voltage. If no voltage
