6.1 Description
The components of the electrical system
are connected by cables, integrated in
four cable harnesses, two front and two
rear and positive/negative cables. The
cable harnesses are connected at one of
the front harnesses (main wiring) with a
connector.
The electrical system consists of several
safety circuits. Therefore certain controls
and pedals are fitted with switches. The
signal from the switches is used to open/
close the circuit when a prohibited action
is to be carried out. For example starting
the machine requires that the parking
brake is depressed and that the operator
is sitting on the seat.
The wiring diagram must be read for full
understanding of the electrical system of
a special machine model. See “6.7” .
All current supply with the exception of
the starter circuit is protected by fuses.
6.1.1 Cable holders
Warning!
It is important that all cable
holders are securely fastened.
If they are not there is a risk of
short circuits and fire.
All electrical cables are mounted on the
chassis with cable holders. When re-
moving or replacing the electrical cables
new cable holders must be installed in
the original positions.
Loose electrical cables can cause
unnecessary wear to the compo-
nents
This can lead to short circuits,
damage to plastic protection,
paintwork etc.
6.2 Fault-tracing
Warning!
Do not wear rings, bracelets,
necklaces or other similar metal
items when working with the
machine electrical system. It
can lead to short circuits or
fires.
This section describes the fault-tracing
procedures when an electrical fault has
occurred in one of the machine functions.
The section also describes what actions
should be taken to rectify the fault. When
the fault tracing schedule is to be used it
is important that the following conditions
are met:
• All fuses must be checked and replaced
if necessary.
• The battery must be charged.
• The conditions for carrying out a proce-
dure must be met. For example, if the
engine is to be started the operator
must be sitting on the seat, the parking
brake must be depressed and the
power take off in the disengaged posi-
tion.
• The engine must be grounded to the
battery negative.
When a fault tracing schedule is to be fol-
lowed it is assumed that the cables are
correctly connected to their terminals. In
certain cases, after a long period of use
or because of mechanical damage, wear
to the cables can occur in, for example,
the pivot point of the machine.
