Turn Indicators Not Working - PIAGGIO Liberty 50 4tempi 2008 Workshop Manual

Liberty 50 4tempi
Electrical system
As the engine rpm increases, so do the current and
the recharge voltage; with rpm over 4000 there
must be a recharge current of about 4.5A; when
the vehicle's lights and stop light are switched on
and the horn is powered, current values ≥ 5A and
a voltage of 14 -14.5V (regulator threshold volt-
age) can be measured.
If values other than those above are detected,
replace the regulator; contrariwise, check the
cable harness and the connections.

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.
