BATTERY: troubleshooting (1/2)
To avoid all risk of sparks:
– Ensure that any electrical consumers (courtesy lights, etc.) are switched
off before disconnecting or recon-
necting the battery.
– When charging, stop the charger before connecting or disconnecting
the battery.
– Do not place metal objects on the battery to avoid creating a short cir-
cuit between the terminals.
– Always wait at least one minute after the engine has been switched off
before disconnecting a battery.
– Make sure that you reconnect the battery terminals after refitting.
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.
Special procedures may be
required to charge some
batteries. Contact your ap-
proved dealer.
Avoid all risk of sparks which may
cause an immediate explosion, and
charge the battery in a well-venti-
lated area. Risk of serious injury.
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. If necessary,
consult a doctor.
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-
