Alternator; Alternator Maintenance - Zetor 86 41 forterra turbo Operator's Manual

ALTERNATOR

The alternator is accessible after dis-
mantling the R.H. side panel. Charging is
monitored with a red warning light at the
combined on-board instrument
In case this signal light bulb of 12 V 2 W
burns, it must be replaced as soon as
possible.
Before repairing the tractor by
means of electrical welding, all
the conductors must be discon-
nected from the alternator. Pro-
tect the "+ B" conductor against
accidental short-circuiting

ALTERNATOR MAINTENANCE

When washing and cleaning the tractor protect the alternator against infiltra-
tion of water or Diesel oil.!
In the course of operation, the alternator may not be disconnected from the
storage battery!
The alternator may never be put in idle run – i.e. with the conductor discon-
nected from the "+B" terminal and the "+D" terminal connected. Such a status
– when increasing the revolutions - would generate extremely high alternator
voltage, which would damaged the semi-conductors installed.
Never short-circuit any alternator terminal during the operation!
The alternator may not be additionally exited. Such an intervention would
destroy the semi-conductors!
Pay attention to the perfect electrical connection at the connecting terminals,
and to the perfect alternator grounding (connection to chassis)!
