2006 FORD TRANSIT Body And Equipment Mounting Section Manual

•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

4.4 Battery and Cables
4.4.1 Battery Information
In order to protect the battery system from direct
ground shorts, a special fuse is incorporated into
the battery positive feed, in the pre-fuse box
under the driver’s seat.
This fuse is not repairable – use only a Ford
replacement part.
Where extra batteries are required on vehicles
with a single battery installation, the battery
disconnect switch (split charge relay) and
associated wiring/hardware — fitted as standard
to vehicles equipped with dual batteries — can
be added.
Batteries – Additional – Heavy Duty
High current consumption may require a
heavy-duty battery or an additional battery.
Factory fitted Special Vehicle Options are available
for heavy-duty and/or extra batteries with the
battery disconnect switch (split charge relay).
The batteries can be retrofitted.
See diagram E74522 - Battery disconnect switch
(split charge relay) circuit.
Deep Cycle Battery (not for use as
primary, start-relevant battery)
A Special Vehicle Option is available. Please
contact your local National Sales Company
representative for availability and details.
•The deep cycle battery is used in conjunction
with the battery disconnect switch (split charge
relay) in applications where power to ancillary
circuits would heavily discharge the main
vehicle battery(s).
•Installation should be under the driver's seat.
When the deep cycle battery is installed, the
battery disconnect switch (split charge relay)
must be used.
•When the Deep Cycle Battery is installed it is
recommended that the Special Vehicle Option
auxiliary fuse box is fed from the customer
connection points.

Battery Rules:
•Batteries in parallel must be of the same type
and capacity.
•Starter and deep cycle batteries may only be
mixed through an isolator.
•For External charging of batteries ensure that
the maximum voltage of 14.6V is not
exceeded.
NOTE: Deep cycle batteries can be drained but
high loads can damage them. Always observe
circuit set-up outlined in diagram E74522 -

Battery Disconnect Switch (Split
Charge Relay)
Where a vehicle is equipped with a single battery,
a split charge option is available. This allows
auxiliary circuits, which would discharge the main
battery system, to be connected to an auxiliary
battery/batteries.
The battery disconnect switch is driven from the
central junction box and is always used with an
auxiliary battery/batteries, and can be fitted by
the vehicle converter. Reconfiguration of the
central junction box software by the Ford
Dealership is required to support this feature.
Where a vehicle already has a factory-fitted
dual-battery system, there is no provision or
need for a further battery cut-off relay, although
additional batteries can still be added in parallel
to the non start-relevant battery.
Outputs from the Central Junction
Box to the Battery Disconnect
Switch
The Battery Disconnect Switch is a bistable
device, requiring pulsed outputs to change state
(each pulse has duration of 50 ms at battery
voltage):
•C4-34 Pull-in
•C4-35 Pull-out

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:

Battery disconnect switch6C1T-10B728-A_
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
options
