No additional connections should be made
directly to the battery terminal posts or Battery
Monitoring Sensor. Further connections should
only be made via the customer connection point.
Camper vehicles: When fitting an additional
battery, this must be connected to the auxiliary
battery circuit. If high loads are to be supplied,
exceeding the customer connection point supplies
or high in general, especially at ignition off loads,
an isolation switch disconnect relay should be
fitted. This is to protect the vehicle start battery
from a failed start. Suitable capacity in the wiring,
fuses and alternator will be required. If unsure of
which battery to interface with or what system
requirements are needed, please contact your
local dealer who can advise.
Refer to: 4.4 Battery and Cables (page 80).
NOTE:
Before disconnecting the battery, check
availability of radio key code.
NOTE:
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 Operation (SVO) auxiliary
fuse panel is recommended.
Refer to: 4.17 Electrical Connectors and
Safety
Increased use of comfort and safety electronics
in modern motor vehicles also requires the
greatest attention to be paid during body work.
Over-voltages produced during welding and in
alignment work during body shell rectification may
cause electronic systems to be damaged. In
particular, the safety instructions for performing
welding / cutting work on vehicles with airbag
systems must be adhered to.
NOTE:
After disconnecting the power supply and
before performing further work, a wait time of up
to 15 minutes must be maintained, depending on
the vehicle. Work on airbag systems may only be
performed by persons who have a relevant
certificate of competence.
Pay attention to the following points:
•
Disconnect all the batteries, including ground
and insulate the negative battery terminal(s).
•
Disconnect the electrical connector at the
airbag control module.
•
Disconnect the alternator multi-plug prior to
using welding or cutting equipment.
•
If welding or cutting is to be performed directly
near a control module, it must be removed
before hand.
•
Never connect the negative cable of the welder
near an airbag or a control module.
•
Connect the negative cable of the welder close
to the location of the weld.
4.3.5 Fitting Equipment Containing
Electric Motors
WARNING: When electric motors are to
be fitted, account must be taken of the
potentially high in rush 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
European Legislation relating to
Electromagnetic Compatibility to ensure
electrical interference does not affect the
vehicle systems.
•
Add EMC emissions statement to CE approval.
4.3.6 Vehicle Electrical Capacity —
Alternator
WARNING: Do not cut into the alternator
wires. The alternator is LIN controlled. It
does not have a conventional D+ (engine
start) signal line.
4.3.7 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.
4.3.8 Circuit Diagrams
For circuit diagrams for Auxiliary Fuse Panel
connections and standard Ford relays.
Refer to: 4.17 Electrical Connectors and
Refer to: 4.15 Fuses and Relays (page 117).
Full vehicle wiring and circuit diagrams are in the
Ford Workshop Manual.
