– Do not connect or disconnect the
terminals of the electronic units while
the ignition key is at MAR.
– Do not check polarity through
sparking.
– Disconnect the electronic units if
you are electrically welding the car
body. Remove the units if tempera-
tures exceed 80°C. (special operations
on the bodywork etc.)
IMPORTANTIf the radio or car
alarm systems are not installed cor-
rectly, they can interfere with the
working of the electronic control
units.ELECTRONIC
CONTROL UNITS
When the car is being used normal-
ly, special measures are not necessary.
The following instructions must be
followed very carefully however, if you
work on the electrical system or in
cases where starting with another bat-
tery is necessary:
– Never disconnect the battery from
the electrical system while the engine
is running.
– When recharging, disconnect the
battery from the wiring system. The
latest battery chargers can, in fact, gen-
erate voltages of up to 20V.
– Never start the engine with a bat-
tery charger. Always use another bat-
tery.
– Be particularly careful when con-
necting the battery to the electrical
system. Ensure the battery posts are
connected up to the right leads (the
polarity is correct) and check that the
connection has been made properly.
Battery Maximum admitted
stand-by intake
50Ah 30 mA
Furthermore, remember that high in-
take electric devices (such as baby bot-
tle warmers, vacuum cleaners, cellular
phones, mini-fridges, etc.) powered
when the engine is off can run the
battery down.
IMPORTANT If you need to install
added systems to the car, improper
wiring connections, in particular if they
affect safety devices, are dangerous.The total intake of these systems
(factory and after-market) must be less
than 0.6 mA x Ah (of the battery) as
shown in the following table:
Modifications or repairs to
the electrical system car-
ried out incorrectly and without
bearing the features of the system
in mind can cause malfunctions
with the risk of fire.
