Electronic Control Units - Lancia Y Owner's Handbook Manual

If, after purchasing the vehicle you
want to install electrical accessories
that require a permanent power sup-
ply (alarm, free-hand phone, radio
navigator with satellite anti theft sys-
tem, etc.) go to a LANCIA Dealer-
ship. The qualified staff are able to
suggest the most suitable Lineacces-
sori devices and will assess the over-
all electric absorption, checking
whether the car can sustain the re-
quired load or if an oversized battery
is required.
Remember that these accessories
continue to absorb electrical power
even when the ignition key is removed
(car parked, engine off) and could
discharge the battery.
134
The overall absorption of these ac-
cessories (standard and after-sale in-
stallations) must be less than 0.6 mA
x Ah (of the battery) as shown in the
table below:
Battery Maximum
capacity idle
intake
40 Ah 24 mA
Remember also that high current in-
take devices such as bottle heater,
vacuum cleaner, cellular phone, re-
frigerator etc., if powered while the
engine is off will accelerate the bat-
tery discharge.
IMPORTANT If you need to install
additional systems on the car, im-
proper wiring connections, in partic-
ular if they affect safety devices, are
dangerous.

When the car is being used nor-
mally, special measures are not nec-
essary.
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 recharging
it. Modern battery chargers can sup-
ply up to 20 volts.
– Never perform emergency starts
with a battery charger. Always use an
auxiliary battery.
– Be particularly careful when con-
necting the battery to the electrical sys-
tem. Ensure the battery posts are con-
nected up to the right leads (the polar-
ity is correct) and check that the con-
nection has been made properly. When
