engine FORD TRANSIT 2006 7.G Body And Equipment Mounting Section Manual

Electrical circuits associated with Management System
•The base vehicle will be equipped with a single
or dual battery system (with battery disconnect
switch). Additional batteries can be fitted in
conjunction with a battery disconnect switch
(cut-off relay), described in the section Battery
and Cables.
•When auxiliary electrical systems are added
to the vehicle, it is recommended that the
additional circuits are designed to be used with
the Special Vehicle Option Auxiliary Fuse Box
and / or the Link Harnesses, to maintain the
integrity of the electrical system.
Refer to: 4.13 Fuses and Relays (page 119).
•The materials and installation must meet the
quality standards described in this section.
•Any additional equipment or components must
be designed such that they have no Electro
Motive Force effect on the vehicle.
•The alternator and Engine Management
System [EMS, also referred to as Powertrain
Control Module (PCM)] are interdependent.
•The alternator should not be used as a source
for a conventional D+ signal.
Refer to: 4.14 Special Conversions (page 131).
•Take special care with the routing of existing
electrical looms within the vehicle to avoid
damage when fitting additional equipment.
WARNING: The fitting of voltage
boosters or other devices to
enhance alternator output are not
allowed. The fitting of such devices
will not only invalidate vehicle
warranties, but could damage either,
or both, the alternator and Engine
Management System or Powertrain
Control Module (PCM), and possibly
affect vehicle legal compliance.
Check local legislation.
Please see below the note concerning installation
of equipment containing an electric motor.
Where vehicles are equipped with twin battery
system, no additional connections should be
made to the terminal posts of the start relevant
battery. Further connections should only be made
via the customer connection point.
When an additional battery is fitted, this must be
connected to the appropriate battery.
Refer to: 4.4 Battery and Cables (page 98).
Disconnect all batteries, including earth, and the
alternator multi-plug prior to using welding or
cutting equipment and before working on any
electrical installations.

•Before disconnecting the battery, check
availability of radio key code.
•Fuses – when auxiliary electrical systems are
to be added to the vehicle it is mandatory that
the additional circuit design includes the
necessary fuses.
•The Special Vehicle Option auxiliary fuse box
is recommended.
Refer to: 4.13 Fuses and Relays (page 119).
4.3.4 Fitting of Equipment
Containing an Electric Motor
WARNINGS:
When equipment containing an
electrical motor is connected, it
must be connected via a blocking
diode or relay to prevent “back
Electro Motive Force (EMF)” being
applied to the auxiliary terminal.
When electric motors are to be
fitted, account must be taken of the
potentially high currents that a
motor can draw.
CAUTION: The following must be
observed:
•All motors must be driven via relays with
contacts rated at least 3 times the maximum
rated current of the motor.
•All motor supply circuits must be individually
fused with the proper fuse rating for the
motor.
•All power wiring must be rated for at least 3
times the rating of the motor and installed as
far away as possible from any existing vehicle
wiring.
•All motors fitted should be fully suppressed to
ensure electrical interference does not affect
the vehicle systems.
•Add EMC emissions statement to CE
approval.
4.3.5 Vehicle Electrical Capacity
- Alternator
WARNING: Do not cut into the
alternator wires or use the
alternator as a source to obtain a
'D+ Signal'
An engine run signal is available from the Central
Junction Box by installing a T-piece jumper
harness (Ford Part Number 6C1V-14A411-F_).
Refer to: 4.14 Special Conversions (page 131).
4.3.6 Charge Balance Guidelines
The base vehicle is fitted with a 150A alternator.
It is recommended to conduct a charge balance
calculation in case the conversion comprises a
high number of electrical consumers or high
electrical consumption is expected.
4.3.7 Circuit Diagrams
For circuit diagrams for Auxiliary Fuse Box
Connections and Standard Ford relays.
Refer to: 4.13 Fuses and Relays (page 119).
Full vehicle wiring and circuit diagrams are in the
Ford Workshop Manual.
NOTE: For further information please contact
your local National Sales Company
representative, or Local Ford Dealer. If they are
unable to help you then please contact the

Pull-in us actuvated within 70 ms of switching to
key position II
Pull-out is activated when switching to key
position I, or 0, and in key position II when no
engine run signal is sensed within 120 secs.
It is not possible to change state within 500 ms.
Removal of the Battery Disconnect
Switch (on twin battery models) and
wiring of batteries in parallel for high
current applications.
For vehicles equipped with a twin battery system,
wiring of the two batteries in parallel is not
recommended. If higher current is required,
680Ah batteries can be fitted (or a deep cycle
battery in lieu of the non-start relevant battery
only). Where a single passenger seat is fitted,
further batteries (1 or 2) can be installed in the
pedestal and added in parallel to the
non-start-relevant battery, although due
consideration then needs to be given to
increased current availability in the event of a
short circuit. Additional batteries should not be
installed under a passenger bench seat.
if this requirement is imperative, it would be
possible to disconnect the battery disconnect
switch and put the start-relevant and
non-start-relevant batteries in parallel using a
shorting bar (available from the Ford Delerships,
part number 6C1T-14A439-A*). There is one
important consideration when replacing the
battery disconnect switch with a shorting bar:
•Where the vehicle is configured for
twin-battery operation, the Central Junction
Box will detect if the battery disconnect switch
is missing (or has been removed), or the
mating connector short-circuited, and although
the vehicle will be functional, Diagnostic
Trouble Codes will be generated that will
flag-up during service. Hence if a shorting bar
is fitted, the vehicle needs to be reconfigured
(via the Dealership and Dealership Hotline).
Single to Dual Battery Conversion
For vehicles equipped with a single battery, it is
possible to upgrade to a twin battery system -
the connector for the battery disconnect switch
is present on all vehicles. In addition to
reconfiguring the vehicle for twin battery
operation (at a Dealership), the following battery
cables and components are required:

If a requirement exists (camper conversions for
example), it may be viable to order vehicles
installed with a single battery, a battery disconnect
switch, and a kit of harnesses – detailed above –
to be fitted by the installer.
Where required, e.g. for camper conversions,
gas-sealed battery boxes (with exterior venting)
are available. Ford part numbers:
6C1T-10N669-A_ (lefthand); 6C1T-10N669-B_
(right hand); 6C1T-10N725-A_ (lid).
The battery disconnect switch isolates the
auxiliary battery/batteries from the rest of the
base vehicle electrical system when the engine
is stopped.
The battery disconnect switch, together with
associated wiring and hardware, can be fitted as
part of an accessory kit (available from your local
Ford dealer) in the pre-fuse box.

4.4.2 Generator and Alternator

Torque Curve of Alternator
Diagram E75871 shows the torque in Nm which
is required to drive the alternator. The vertical
axis (A) shows the torque [Nm] and the horizontal
axis (B) shows the alternators revolutions per
minute [1/min].
NOTE: For equivalent engine revs per minute
(RPM), the alternators revolutions, axis (B) should
be divided by the following factors: 2.66 for diesel
(2.2L and 2.4L), 2.4 for Gasoline (2.3L).
NOTE: These alternator curves do not show
spare output capacity as this would be
dependant on original vehicle features and

It is recommended that these signals are used
to energize relays, or any other device, as long
as the maximum current does not exceed
300mA per function, or 600mA (suitable for
powering two relays) for the ignition feed.
NOTE: *There is NO direct provision for an air
conditioning on signal. When the air-conditioning
is switched on, 12V is applied to the defrost
compressor switch and the Air conditioning low
speed blower relay (both integral to the heating
ventilation and air conditioning unit and 18B518
wiring), and the Air conditioning cycling switch
(in the engine bay as part of the 9K499 wiring
[via the 14401 and 14K024 harnesses]). Additional
load on this line is limited, so air conditioning on
is only available as a signal (300mA) for voltage
sensing or powering of a relay – powering
another device directly is Not recommended.
Where additional current is required from either
output, a standard relay should be used, please
refer to Relay Figures E75017-E75021.
The Special Vehicle Option Auxiliary Fuse Box is
recommended as the most suitable power
source for these relays. Please consult your local
National Sales Company representative for
availability.
