ELECTRIC INSTALLATION

ALTERNATOR
Charging is monitored by the red indica-
tor on the combined dashboard instru-
ment.
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 penetra-
tion 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!
