– If electrical welding is to be carried

out on the body of the vehicle the elec-

tronic control units must be disconnected

or removed if the work involves the pro-

duction of high temperatures.

The total absorption of these accessories

(standard and installed later) must be

0.6 mA x Ah (of the battery), as shown

in the table below:

Battery

Maximum permissible

loadless absorption

100 Ah 60 mA

You are also reminded that services with

high current absorption activated by the

user, such as bottle warmers, vacuum

cleaners, cellular telephone, mini refriger-

ator, etc. accelerate the battery drainage

process if they are powered with the en-

gine not running.

IMPORTANT It should also be noted

that improper branches on connectors of

the electric wiring for installing additional

equipment is dangerous, particularly if

safety devices are involved.

ELECTRONIC

CONTROL UNITS

With normal use of the vehicle no par-

ticular precautions need to be taken.

If interventions are to be carried out on

the electrical system or emergency start-

ing the following must be heeded:

– Always switch off the engine before

disconnecting the battery from the electri-

cal system.

– If battery charging is necessary dis-

connect it from the electric system.

– When starting in an emergency only

an auxiliary battery must be used and not

a battery charger.

– Check that the polarity is correct and

that the connections between the battery

and the electrical system are sound.

– Before connecting or disconnecting

the terminals of the electronic units en-

sure that the ignition key is not in the

MAR position.

– Do not check for current in the cables

by short-circuiting the ends.

If additional systems are

to be installed on the ve-

hicle the danger of incorrectly tak-

ing branches from the electrical

wires cannot be emphasized too

strongly especially if devices es-

sential to the safety of the vehi-

cle and its occupants are involved

(ignition, injection, ABS ...). The in-

correct installation of radio sys-

tems, electronic theft alarms, ra-

diotelephones etc. can interfere

with the electronic control units and

compromises the warranty cover.

For these interventions we re-com-

mend that you contact Alfa Romeo

Authorized Services.The loadless

absorption of all the accessories in-

stalled in the after market must

not exceed 20 mA (reading with

the vehicle stationary).
