It is accessible after opening of the
bonnet. Recharging of the battery is
indicated by a red light on the dashboard
cluster; this light shall be off after starting
the engine.

shall be immediately replaced by
a lamp of identical parameters.
The indicator is part of the alterna-
tor excitation circuit; in case that
the lamp is burnt, the battery is
not recharged!

MAINTENANCE OF THE ALTERNATOR

During cleaning and washing of the tractor protect the alternator against water
or diesel oil!
Alternator shall not be disconnected from the battery during run of the engine!
Alternator shall not be put into operation without loading, i.e. with the conduc-
tor disconnected from the terminal "+B" and connected terminal "+D". Such
connection may generate extraordinary high voltage in case of increasing of
speed of the engine and such voltage might destroy the semi-conductors!
Never short-circuit any battery terminal during run of the engine!
Alternator shall not be excited additionally. In such case the semi-conductors
may be damaged!
Pay attention to perfect electric connection on the terminals and grounding of
the alternator!
Poles of the alternator may not be reversed even for a short time!
