Turn signals system check

4) TURN INDICATORS NOT WORKING

If the turn indicators do not work, do the following:
- Disconnect the regulator connection and insert
the multimeter probes between the white cable (3)
and the black one (2).
- Turn the key switch to ON and check that the
battery is getting voltage. If no voltage is detected,
repeat the test now between the white cable and
the earth; if there is no voltage even after this op-
eration, check the wiring and the contacts of the
key switch and the battery. If voltage in the battery
is detected (black cable), check the regulator earth
wiring.
- If the above tests have positive results, jump the
contacts 5 (blue/black) and 3 (white) on the con-
nector, set the key switch to ON and the turn
indicator switch left and right to see when the lights
are steadily on (as they are powered directly from
the battery).
If even after this operation the turn indicators fail
to turn on, check that the wiring is not damaged
and the switch works properly. If these last two
tests have a positive result, replace the regulator
because it is certainly not functioning properly.
