Never disconnect the batteries from the
system with the engine running.
When needing to disconnect the batteries from the
system, always firstly disconnect the frame earth cable
from the negative terminal of the batteries.
Before connecting the batteries to the system, make
sure that the system is well insulated.
Disconnect the batteries from the system when
charging them.
The purpose of the electric system is to generate,
regulate, store and distribute the energy needed to make
the vehicle components work.
For this reason the supply of the base electric system
is ensured by a generator (28V - 60A -90A alternator)
and two batteries, each with 12 V 110 Ah (143 Ah - 170
Ah) connected in series.
A mobile fuse holder containing a 20 Amp fuse is
located close to the batteries. This fuse supplies:
-
Fuse holder 70601/C
-
Body Computer (J1-8)
-
Cluster (B20)
-
Tachograph (A1)
-
Diagnosis connector (Pin 27)
This fuse is not present on the ADR version.

remaining sections.
Negative network
The batteries are connected to the frame earth with
a brown 70 mm
2
cable, at earth point M1 on the left
sidemember (Fig. II.3).
The starter motor is connected to the frame earth
(M2) through a 70 mm
2
cable, fastened on the right
sidemember, near the actual motor. The same cable
serves for connecting the whole engine unit to the frame
earth.
The same electric, negative equipotentiality of the
chassis is made available to the vehicle cab by means of
a stranded wire connected to the cab front and the front
right side member.

Though generally protected against the influence of on-board equipment voltage, electronic components nevertheless
remain particularly sensitive electromagnetic compatibility issues, of different nature such as:
-
generated by the vehicles
-
external.
A suitable size flexible electrolytic copper braid has been provided on the vehicles to minimize these phenomena and
return main cab and frame structures to the equipotential state.
Check that the braid is properly attached to the frame and the cab, in the event of defective cab grounding.
