Electrical system
Battery connection
— The battery terminals must never be confused. Each terminal is
clearly marked with a (+) or a (-) sign respectively. If the cables
are wrongly connected, the alternator rectifier will be ruined im-
mediately.
— When disconnecting batteries, first break the circuit using the
battery master switch. See
Master switch
on page 177.
Electric welding
— Before electric welding is carried out on the machine or any at-
tachment installed to the machine, the current must be turned
OFF at the battery master switch.
— Before carrying out any electric welding on the machine, the
battery cables should be disconnected and the connectors
pulled out of the electronic control units.
— When disconnecting and reconnecting, the leads should be
without current (the battery master switch turned off).
— Connect the earth (ground) lead of the welding equipment as
close to the welding point as possible.
— Before welding, remove all paint from an area of at least 10 cm
(4 in) around the point of welding. Paint which is heated gives
off unhealthy gases.
— All paint decomposes when heated and forms a great number
of compounds, which may cause irritation and be dangerous to
ones health after repeated or prolonged exposure.
— In addition to the health hazard, the weld will be of inferior qual-
ity and strength, which, in the future, may cause the weld to
break. Therefore, never weld directly on a painted surface.
Electrical distribution box
General
The machine has an electrical distribution box (A) installed to the
right of the operator seat. The electrical distribution box contains
most of the fuses and relays of the machine.
WARNING!
Never install a fuse with a higher ampere rating than that
stated on the decal (risk of damage or fire on the circuit
board).
If a fuse blows repeatedly in the same position, the cause of
the fault has to be investigated.
