1. CHARGING CIRCUIT/STARTING MOTOR/CONTACT/STARTER SWITCH
CONTACT CIRCUIT
If a connection is made between contacts 1 and
6 with contact/starter switch C539, a voltage is
applied through fuse E037, switch C539 and
wire 1130 to contact 85 of relay G178.
Because relay G178 is activated, a connection is
made between contacts 30 and 87 and a
voltage is applied through fuse E037, wire 1100,
the contacts 30 and 87 of relay G178, wire 1147,
and through fuses E027 and E052 to the
electronic unit of converter 24 V/12V D525 and
the work light switch C725.
If a connection is made between contacts 1 and
4 with contact/starter switch C539, a voltage is
applied through fuse E037, wire 1100, switch
C539 and wire 4001 to contact 85 of relay G015.
As a result, relay G015 is activated, so that wire
1000 is connected to wire 1010. Now voltage is
applied to the supply behind contact circuit
(connection point 1010) and, through resistor
B036 and diode D668, to the connection points
D+ of the alternator A502, connection point 85 of
relay G303 and to the electronic unit CWS
D853.
START CIRCUIT
When the engine is started, a connection is
made between the contacts 1 and 2 with
contact/starter switch C539. The voltage now
runs from the batteries through wire 1000, fuse
E037, connection 1–2 of the contact/starter
switch, wire 4002 and contacts 30 and 87 of
relay G303, wire 4009, to connection point 50 of
starting motor B010. The coil of the starting
motor relay is now activated, so that a voltage is
supplied to the starting motor, as a result of
which the motor will start operating.
As soon as the engine is running, the voltage on
connection D+ of the alternator will increase to
the adjustment voltage (= board voltage). This
voltage will cause the coil of relay G303 to be
energised. It will break the connection between
30 and 87A and connects 30 to 87. As a result,
wire 4002 is disconnected from wire 4009. In
this situation it is no longer possible to start.

CHARGING CIRCUIT
If the contact is activated, a voltage is applied to
resistor D+ B036.
The other side of the resistor is connected to the
D+ connection of the alternator through diode
D668 and wire 1020.
The D+ connection is connected to earth
through the integrated voltage regulator in the
alternator A502. This will cause a small current
to run, causing a magnetic field in the alternator.
After starting, the voltage on clamps B+ and D+
will increase to approx. 29 V. This is caused by
the fact that the regulator disconnects the earth
connection in the regulator and connects it to
the battery voltage. This voltage is also applied
to wire 1020, so that the difference of potential
over the resistor becomes 0 V. The magnetic
field now disappears, so that the generator is
not activated for a short time. This will reduce
the voltage on outputs B+ and D+.
The regulator is activated if the voltage drops
below 27.6 V. This way, the generator voltage
supply remains relatively constant. The batteries
are fed by generator output B+.
