General instructions for chassis modifications
Regarding the electrical equipment remember to:
a) Take precautions concerning the alternator and the electrical/electronic components. In order to avoid damaging the diode
rectifier, never disconnect the batteries (or open the isolator) when the engine is running.
If the vehicle has to be tow started make certain that the batteries are connected. Should it be necessary to quick charge
the batteries, disconnect them from the vehicle circuit.
In order to run the engine with external means and in order to avoid current peaks which might damage the electric/elec-
tronic components, do not use the ”start” function in conjunction with external charge devices if such devices are equipped
with this function. Starting will have to be carried out only with the external battery trolley ensuring correct polarity.
b) Checking the earth connections.
As a general rule the original earth connections of the vehicle must not be changed. If it is necessary to move these connec-
tions or to implement further earth points use the existing holes on the chassis as far as possible and:
- Remove, mechanically, and/or with an appropriate chemical product, the paint on the chassis side and on the terminal side
creating a resting plane free from indentations or ridges.
- Apply appropriate high conductivity paint between the cable terminal and the metal surface (e.g. galvanizing paint IVECO
Part number 459622 by PPG).
- Connect the earth cables within 5 minutes from the application of the paint.
Do not use the IVECO standardised M1 (battery earth connection) M2, M8 (earth connection for starter motor depending on the
driving position) points for the earth connections for control switches (e.g. sensors or low absorption devices): See IVECO Work-
shop manuals.
With regard to the electronic devices, avoid linking earth connections between the devices; only use single wire earths with optimised
lengths (as short as possible).
c) Electric wiring
