Engine electrical ground
The connection of the engine electrical ground is achieved
by connecting with a cable of at least 70 mm
to the negative pole of the battery to the tightening point of
the electric starter motor as shown in Figure 39.
On the same terminal it is necessary to connect the eye
battery lead connection marked with "- BAT (MM)".

the negative pole.
To anchor the grounding terminal to the engine, proceed as
follows:
Completely remove the conducting paint from both parts
constituting the connection, using mechanical means or
suitable chemical product; if the anchoring operation is to
take place on superficially treated parts, completely remove
the anaphoretic paint with mechanical means, obtaining a
smooth support surface.
IVECO standard 18-1705:
Apply a uniform layer of BH44D paint with a brush or spray
gun.
Join the parts constituting the grounding note within 5 min-
utes from the time the paint was applied.

This is accomplished through the power supply line of the
06_008_N
electric starter motor and connection to the +B of the
alternator. The electronic regulator of the alternator that
equips the engine allows an effective control over the battery
recharging operation.
If, due to installation requirements, the batteries need to be
positioned at a distance from the engine, we recommend
increasing the cross section of the power line conductors and
verifying recharging effectiveness by measuring voltage across
the battery poles.
Verification of the engine rotation over speed
This function is carried out by the specific J16F module, which is
connected to the engine wiring on the JSV connector through
the JSV-J16F extension lead. This module is able to recognize
the over speed condition and to command the activation of
the relating signal on the instrument board.
The consequent engine stop is carried out by the specific
circuits situated in the main board supplied by IVECO
MOTORS or in the Signalling and Alarms module supplied
by IVECO MOTORS to carry out personalized boards. In
both cases the electronic commands a relay which is used to
manage the supply of the engine stopping electro-valve.
To produce the boards which do not use the above mentioned
components supplied by IVECO MOTORS, it is necessary to
use similar circuits which carry out the required function.
