Start the engine (temporarily connect the red cable
to the battery positive terminal in order to avoid
damaging the device that measures current).
Check that there is a 13V voltage minimum (bat-
tery charged) and a recharge current of 1.5 ÷ 2A
with the lighting system but the starter disabled. To
disable the lighting system, remove the light re-
mote control.
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; enabling
both the lighting system and the starter, the stop
light and if the horn is powered, current values
≥
5A and a voltage value of 14 ÷ 14.5V ( regulator
threshold voltage) can be found.
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:
- Remove the regulator connector and place the
tester probes between the orange cable (3) and
the black cable (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 orange cable and
the ground lead. If there is no voltage even after
this operation, check the cable harness and the
contacts of the key switch and the battery. Con-
versely, if battery voltage is detected (black cable),
check the regulator ground cable harness.
