Water presence in the filter sensor
1. filter - 2. Conductor to be connected
with the negative battery terminal.
CAUTION
In order to enable the proper working of the sensor to
detect water in the fuel, it is necessary that the filter
support is connected electrically to the negative battery
terminal.
In the engine models which use parts with insulated poles it
is necessary to electrically insulate the filter support from the
boat mass and then connect the support with the negative
battery terminal.

Heater plug fuse
A maxi 60 A fuse is located in serial connection with the
electric network of heater plugs.
Diagnostic connector
A multipolar plug is located in proximity of the relay box,
to which an IVECO MOTORS diagnostic tool can be con-
nected to.
The diagnostic tool allows the processing of data recorded
during the engine operation phase and memorized in the
ECU; data interpretation will provide useful indications to
better schedule maintenance interventions.
Throttle lever position sensor
After testing the working condition of the linkage, adjust the
run of the servo components (see Chapter 18).
o With the throttle at idle setting, the potentiometer rod
has to be in the resting position.
o With the throttle at the stop, the potentiometer rod has
to be in the position of maximum run out.
