Voltage regulator check
A malfunction in the voltage regulator might cause the following problems depending on the type of
fault:
1) Bulbs burned out (regulator in short circuit).
2) Malfunction of the lighting system and the electric starter (regulator interrupted).
3) Battery not recharging.
4) Turn indicators not working.
The regulator is earthed through the electrical system, so the regulator body does not earth the circuits
inside the regulator.
There must be insulation between each regulator terminal and the regulator body (use the tester to
check electric resistance).
2) LIGHTS AND STARTER NOT WORKING
Gain access to the voltage regulator by removing
the plastic cover on the legshield; start the engine
and keep running it at idle speed.
Connect the tester positive probe to terminal No.
1 (yellow cable) and the negative probe to terminal
No. 2 (black cable); check if there is voltage.
If there is voltage, check that the light remote con-
trol and its excitation line, coming from the elec-
tronic starter (sky blue PIN 7 - purple PIN 3) work
properly. Check the cable harness from the light
switch to the remote control and whether the
switch works properly .
If no voltage is detected, try connecting the nega-
tive probe directly to earth; if voltage is detected
with this operation, check the earth wiring of the
regulator; otherwise, replace the regulator be-
cause it is failing.
As a last check, the voltage supplied by the stator
can be measured:
- Disconnect the regulator connector and place a
tester to detect alternating voltage between the
Blue cable (4) and the ground connection (see fig-
ure).
