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 tester end 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 turn 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 the wiring is not
damaged and switch works properly; If these last
two tests have a positive result, replace the regu-
lator because it is certainly not functioning proper-
ly.
