Electrical system
If no voltage is detected, connect the multimeter
negative lead to the ground connection and the
positive lead to the automatic starter White-Black
cable; with the key switch set to «ON» check
whether there is battery voltage; if there is no volt-
age, check the connection cable harness to the
key switch and that the 15A fuse (No. 7) works
properly.
If there is voltage, check again the ignition control
unit connector.
After disconnecting the starter, start up the engine
and keep it at idle speed; then check whether there
is voltage connecting the multimeter positive lead
to terminal No. 5 (Green-Red), and the negative
one to terminal No. 7 (White-Black) (see figure).
If there is no voltage, replace the control unit after
making sure that the fuses are not blown; other-
wise, check the cable harness between the starter
and the control unit and, as a last resource, re-
place the starter.
Turn signals system check
- If the turn indicators do not work, proceed as fol-
lows:
- Disconnect the control unit connector and check
that there is battery voltage between terminal No.
4 (Red-Black) and the ground lead.
- Check that the same happens between terminals
No. 4 and No. 8 (Black).
- Repeat the check between terminal No. 5
(Green-Red) and terminal No. 8 (Black) with the
key switch set to «ON», the side stand up and the
emergency switch set to «RUN».
