After disconnecting the choke device, start the engine
and keep it idling. Check for the presence of voltage
by connecting the multimeter positive terminal to the
terminal no. 5 (light blue) and its negative terminal to
terminal no. 7 (white/black) (see figure).
If no voltage is detected, replace the control unit
after verifying the integrity of the fuses, otherwise
check the wiring between the choke and the
electronic control unit, and if necessary proceed by
replacing the choke device.

Turn Signal Lights Fail to Operate
If the turn signal lights fail to operate, proceed as
follows:
-
Detach the control unit connector and check for
potential difference at terminal no. 4 (red/black)
with respect to ground (p.d. must be equal to
battery voltage).
-
Check that the same p.d. (battery voltage) is
present between terminals no. 4 and no. 8 (black).
-
Repeat the same check between terminals no. 5
(light blue) and no. 8 (black) with the ignition
switch turned to the «ON» position, and the
emergency cut -off switch in the «RUN» position.

If no voltage is detected, check the wiring, the
connections and the integrity of the main 15A fuse;
otherwise proceed as follows:
-
Jumper terminals no. 1 (black/blue) and no. 4
(red/black) as shown in the figure. Acting on the
turn signal switch, ensure that the turn signal
lights come on
-
If so, the control the control unit is defective and
must be replaced. Otherwise check the wiring
between the control unit and the turn signal
switch, and then repeat the test
-
If the wiring is intact and the turn signal lights still
fail to operate correctly, replace the turn signal
switch.
