BATTERY: troubleshooting (1/2)
To avoid all risk of sparks:
– Ensure that any consumers (cour- tesy lights, etc.) are switched off
before disconnecting or reconnect-
ing the battery;
–
w
hen charging, stop the charger
before connecting or disconnecting
the battery;
–
t
o avoid creating a short circuit be-
tween the terminals, do not place
metal objects on the battery;
–
always
wait at least one minute after
the engine has been switched off
before disconnecting a battery;
–
m
ake sure that you reconnect the
battery terminals after refitting.
Handle the battery with care
as it contains sulphuric acid,
which must not come into
contact with eyes or skin. If
it does, wash the affected area with
plenty of cold water and consult a
doctor, if necessary.
Ensure that naked flames, red hot
objects and sparks do not come into
contact with the battery as there is a
risk of explosion.
The engine may be hot when car-
rying out operations in close prox-
imity. In addition, the engine cooling
fan can come on at any moment.
Risk of injury.
Connecting a battery charger
The battery charger must be com-
patible with a battery with nominal
voltage of 12 volts.
Do not disconnect the battery when the
engine is running. Follow the instruc-
tions given by the manufacturer of
the battery charger you are using.
When many accessories are fitted to
the vehicle, have them connected to
the + after ignition feed.
Some batteries may have
specific conditions for re-
charging. Consult your ap-
proved dealer. Avoid the
risk of sparks, as this could cause
a sudden explosion, and always
charge the battery in a well-venti-
lated area.
Risk of serious injury.
