Electrical system
(FIG. G) If the above tests have positive results,
jump the contacts 5 (yellow/red) and 7 (blue/black)
on the connector, set the key switch to ON and
shift the turn indicator switch to the right and left 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 pos-
itive result, replace the regulator because it is cer-
tainly not functioning properly.
FAULT 6
Oil reserve check warning light not working
(FIG H) - Disconnect the voltage regulator con-
nector.
- Supply 12V to the terminal marked with number
5; with a digital tester check that the terminal num-
ber 4 has a similar output (12V) for about 5 sec-
onds.
- If no voltage is detected for terminal number 4,
replace the regulator.
- If there is voltage for terminal number 4, check
both the installation and the bulb of the oil warning
light.

INSTRUCTIONS FOR REFRESHING THE STOCK CHARGE OF AN OPEN CIRCUIT
1) Voltage check
Before installing the battery on the vehicle, check the open circuit voltage with a normal tester.
- If the voltage exceeds 12.60 V, the battery may be installed without any renewal recharge.
- If voltage is below 12.60 V, a renewal recharge is required as explained in 2).
2) Constant voltage battery charge mode
-Constant voltage equal to 14.40÷14.70V
-Initial charge voltage equal to 0.3÷0.5 for nominal capacity
-Duration of the charge: 10 to 12 h recommended
Minimum 6 h
