7.3 SAFETY MICROSWITCHES OPERATION
CHECK
This check is made by detaching all the connectors
and by using the tester in the Ohm-meter function.
This operation should be done, without the driver
on board, by making contact with the ferrules on
the contacts of the female connector of the wiring
(1)and should give this result:
N° Contacts Tester reading and condition

7.4 TERMINAL BOARD SUPPLY CHECK
This check is done with the tester in voltmeter func-
tion (Volt DC 0 ÷ 20), with the black ferrule on termi-
nal 3 (CN5) and the red ferrule on terminal 2 (CN3 )
the wiring connectors 
(1).
–The key in the «ON» position.
The reading shows the battery voltage, which
should never go below 11 Volts.

7.6 STARTER RELAY OPERATION CHECK
WARNING! – Remove the cap of the sparking
plug (or plugs), since the safety systems that
normally prevent accidental starting of the
engine are cut out when the checking procedure
is carried out.
To do this requires:
–engaging the parking brake;
–disengaging the blade;
–the key in the «ON» position.
Disconnect the connector CN3.
In making a bridge...

7.7 ELECTRONIC CARD OPERATION CHECK
A) Card supply
To make this test it is necessary to have:
–The key in the «ON» position
–Connector CN2 
(1)disconnected from the card,
with all the other connectors attached.
In this situation the pilot lamp should come on.
If the indicator light goes out when connector 
(1)is
inserted, the earth connections of the microswitch-
es must be checked.
B) Safety and service supply check
This check is done with the tester in the Voltmeter
function (Volt DC 0 ÷ 20), with the...

7.8 RECHARGE CIRCUIT CHECK
The job of the voltage regulator is to supply a flow of current to the battery at a constant voltage of about 14 -
15 Volts, cutting in every time that the output voltage from the generator exceeds this threshold.
A faulty regulator may recharge the battery insufficiently (therefore needing frequent recharging) or, otherwise,
may supply overloading that causes the self-resetting protection to cut in.
Before checking the recharge circuit, make sure that:
– all connections...

7.9 CARE AND MAINTENANCE OF THE SEALED BATTERY
A) General information
In a sealed “dual” battery, the electrolyte for each element is carefully measured out during manufacture and
sealed at source, in order to ensure maximum performance during the battery’s entire life.
With a battery of this type, it is not necessary to add water or acid, and the cover must never be opened or
removed.
B) Recommendations for correct use
To keep the battery performing at optimum levels and to increase its life,...
