ELECTRIC INSTALLATION

ALTERNATOR
The alternator is accessible after opening
of the hood. Proper charging is signalled
by the red indicator on the combined
dashboard instrument, which must go off
after starting.
The burnt 12V / 2W indicator
lamp must be immediately re-
placed with a lamp of the same
parameters. The indicator is part
of the exciting circuit of the alter-
nator. If the indicator lamp is
burnt, the battery is not charged!
During repairs of the tractor by
electric welding all the conductors
must be disconnected from the
alternator. Protect the “+B” con-
ductor from a short-circuit.
ALTERNATOR MAINTENANCE
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 con-
ductor 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!
The polarity of the alternator must not be reversed even for a short time!
