CAR MAINTENANCE

These devices will, in fact, run off the
battery even when the key is not in-
serted (car parked) and can deploy the
battery.
The total intake of these systems
(factory and after-market) must be less
than a 0.6 mA x Ah (of the battery), as
shown in the following table:
Battery:
50 Ah
60 Ah
70 AhMaximum
admitted
stand-by intake:
30 mA
36 mA
42 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 deploy the
battery.
IMPORTANTIf you need to fit ad-
ditional systems in the car, remember
that improper wiring connections, in
particular if they affect safety devices,
are dangerous.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 emergency starting is
necessary:
– never disconnect the battery from
the electrical system while the engine
is running.
– disconnect the battery from the
electrical system if you are recharg-
ing it.
– never perform emergency start-
ups with a battery charger. Always use
an auxiliary battery.
– be particularly careful when con-
necting the battery to the electrical
system. Make sure that the polarity is
correct and that the connection is ef-
ficient.
– before connecting/disconnecting
the electronic unit terminals make
sure the ignition key.
