Additional circuits
The additional circuits must be separated from the vehicle and protected by means of a specific fuse
As already seen in the Paragraph "Precautions for work on the system", the used cables must be:
● of appropriate sizes and equipped with good original insulation;
● connected to the original system by means of tin joints equivalent to the original ones, protected with sheaths (not PVC) or
intubated in polyamide conduits of type 6;
● installed protections from shock, heat, rubbing with other components (in particular with the sharp edges of the bodywork);
● secured separately with insulated cable clamps (e.g. nylon) and at suitable intervals (approx. 200 mm).
The passage through crossbars and/or sections must provide special fairleads or protections; it is not possible to drill the chassis
and/or the bodywork.
In case of external panels, use a specific sealant both on the cable and on the panel to prevent water, dust and fumes from infiltrat-
ing.
Where possible it shall also be provided a different cable path that transfers interference signals with high absorbed intensity (e.g.
electric motor, solenoid valves) and low absorbed intensity susceptible signals (e.g. sensors); for both must be remained a position-
ing as close as possible to the metallic structure of the vehicle.
Plug and terminal connections must be protected, resistant to weathering, and executed using components of the same type as
those utilised originally on the vehicle.
Use cables and fuses with the characteristics shown in the following table in accordance with the current draw:
