FEBRUARY 2003 EDITION
Battery recharge
The electronic regulator of the alternator supplied with the
engine can effectively control battery recharge through the
S
terminal of the three-pole connector.
For reasons related to the test bench testing phase, this ter-
minal’s line is connected to the positive polarity of the elec-
trical system, meeting the need to control the recharge of
batteries located near the engine.
If different installation needs require to connect the batteries
far from the engine, we recommend changing this connec-
tion, cabling the line relating to the
S terminal of the alterna-
tor directly to the positive terminal of the battery.
Instrument and control panel
Supplied on request by IVECO Aifo, this is connected to the
EMB with three different lengths of wiring as indicated in the
item that follows.
Technical information and data for the manufacture of pan-
els by the Yard must be requested from the IVECO Aifo
technical assistance service.
Connecting cable between the indication
panel and the EMB
Supplied by IVECO Aifo on request, it is available in 3 differ-
ent lengths:
❏
3 meters: Drawing 8031150
❏
5 meters: Drawing 8031151
❏
7 meters: Drawing 8031152
Throttle position sensor
After testing the operating condition of the linkage, adjust
the stroke of servo components so that:
❏
With the throttle at idle, the potentiometer rod is in the
resting position and the safety switch inside is electrical-
ly open.
The test must be conducted with an ohmmeter
between the points D and E of the potentiometer con-
nector.
With readings of:
∞ Ω
= optimal adjustment
1 K
Ω
= the resting position requires better mechanical
adjustment, to bring the value back to
∞ Ω
❏
With the throttle at the maximum rpm stop, the rod of
the potentiometer is in the maximum travel position.
Technical notes for Yard wiring are provided at the end of
this section.
