FAULT 4
a) By positioning tester 020331Y between the yel-
low wire terminal (8) on the regulator and the black
wire (6) (FIG. D), check the generator output volt-
age is within 26 and 30 V at 3,000 rpm (this meas-
urement must be carried out with the battery
detached). In the event of anomalies, replace the
stator; otherwise proceed to point b).
b) Yellow wire (1) attached to the regulator. Insert
an ammeter between the stator's blue wire (2) and
the battery, and check, using tester 020331Y, that
the current output, at 3,000 rpm and with the bat-
tery kept between 12 and 13V, is approx. 1.5 - 2 A
(FIG. C).
If the values thus obtained are lower than prescri-
bed, proceed by replacing the regulator. Before
carrying out inspections on the regulator and its
electrical system, it is always advisable to check
for continuity between the black wire and earth.
FAULT 5
(FIG. E) If the turn indicators do not work, proceed
as follows:
- Remove the regulator connector, and insert the
tester probes between the contact 5 (yellow-red)
and the ground lead.
- Turn the key switch to ON and check that the
battery is getting voltage. If no voltage is detected,
check the wiring and the contacts on the key
switch and on the battery.
(FIG. F) Repeat the procedure now placing the
tester probes between contacts 5 (yellow/ red) and
6 (black), and check the presence of the battery
voltage with the key switch set to ON. If there is no
voltage, check the regulator ground wiring.
