Electrical System: Modifications and Drawing-Off Power
When fitting additional equipment, where necessary, diodes must be fitted to provide protection against an y induction current peaks.
The earth signal originating from analogu e sensors must only be wired to a specific receiver. Additional earth connec tions could
result in false output signals being emitted from these sensors.
The wiring looms for th e electronic components with low in ten sity signals must be arranged in parallel t o th e metal datum plane
i.e. it must adhere to the chassis/cab structure in order to reduce the parasite capacity. It should be spaced from additional wiring
loomsasfaraspossible.
Additional equipment should be connected to the system earth with the u tmost care (see point 2.1.1). The relative wiring must
not be fitted alongside the existing electronic circuits in order to avoid electromagnetic interference.
The wiring of th e electronic systems (length, conductor type, arrangement, clamping, connecting sh ield braids etc.) must follow the
original IVECO standards. Carefully reset the original system after carrying out any work.
Engine starting
Never start the vehicle by towing.
Do not start the engine without first disconnecting the batteries permanently.
If the batteries require charging, disconnect them from the vehicle circuit.
If starting usin g auxiliary methods, th is must be carried ou t only using an external battery trolley in acc ordance with the following
procedure:
- To prevent damage to the vehicle, it is important to ensure the tanks contain sufficient fuel during start-up. Attempting to start
the engine with insufficient fuel could cause serious damage to the injection system.
- O bserve all current accident prevention precautions (including the use of gloves).
- Use a battery trolley with specifications similar to those of the vehicle battery.
- Use an appropriate cable to connect the battery trolley positive terminal to the positive terminal of the CBA fitted on the vehicle
battery positive terminal.
- Use a suitable c able to connect the negative terminal of the charged battery to the earth of the vehicle with the flat battery.
- TWhen starting the engine on vehicles with a manual gearbox: turn the key ON and wait for all the engine warning lights on
the instrument panel to go off. Start the vehicle engine. The starter motor must not be used for longer than 10 seconds. Do
not depress the accelerator pedal during start-up.
- When starting the engine on vehicles with an automatic gearbox: turn the key ON and press the brake pedal. Wait for all the
engine warning lights on th e dashboard t o go off and for a ” Gearbox OK” message to appear on the display. Start the vehicle
engine. The starter motor must not be used for longer than 10 seconds. Do not depress the accelerator pedal during start-up.
- Wait for th e vehicle engine to reach idling speed.
- Do not t urn on any vehicle electrical appliances, e.g. low beams, heater. This will prevent any current peaks and damage to electric
control units when the battery trolley is disconnected.
- Firstly disconnect the vehicle negative terminal and then the battery trolley negative terminal.
- First disconnect the CBA cable fitted to the vehicle battery positive terminal and th en the battery trolley positive terminal.
