Electrical system: modifications and drawing-off power
Supplementary batteries
The insertion of a supplementary battery into the vehicle circuit requires a separate charging system, integrated with that of the
vehicle. In this case, supplementary batteries must be provided with an equal capacity to those fitted originally (110 Ah) for correct
charging of all the batteries.
If the supplementary battery is installed, it is possible to use:
a) recombination batteries (AGM or gel)
b) traditional batteries.
In both cases, the battery must be completely separated from the occupants in the vehicle. A suitable air tight container could be
used in case of:
- vapour escape (e.g. in case of alternator voltage regulator failure);
- battery explosion;
- electrolyte leaks, even in case of vehicle overturning.
In the event that type a) batteries are used:
- a vent to the passenger compartment exterior shall be provided.
In the event that type b) batteries are installed, the batteries shall be equipped with:
- a cover with a system for blowing the gas off to the outside, fitted with tube for conveying the acid spray to the outside;
- a flame anti-return system by means of a porous pellet (flame arrester).
Moreover, gas escape shall take place far from points liable to spark ignition as well as mechanic/electric/electronic members and
parts. The exhaust shall be positioned in such a way that vacuum shall not be generated inside the battery.
!
Ground connection of the added battery shall be made by using a cable of adequate section, as short
as possible.
