Page: 120 / 176

When washing and cleaning the tractor protect the alternator from penetration of water or
diesel fuel! During operation the alternator must not be disconnected from the battery! The alternator
must never be put in operation without load, i.e. with the conductor disconnected from the '+B'
terminal and the '+D' terminal connected. Such a condition may induce an extremely high voltage
when the engine speed is increased, which would destroy the semiconductors! Never short-circuit
any alternator terminal during operation! The alternator must not be additionally excited. Such an
intervention would damage the semiconductors. Ensure perfect electric connection of the alternator
terminals and proper grounding of the alternator! Poles of the alternator may not be re-versed even
for a short time!
Charging control
Fuse box
Charging control has two functions.
If there is:
1 - red light with the engine running, it is a charging
failure,
2 - orange light signalizes a state when electrical
installation of tractor has such intake that the performance
of alternator is insufficient for charging the accumulator.
If this condition occurs, turn an appliance off
and the control is off.
The engine operation with a lit orange charging control
can result in accumulator depletion.
