Starter - Allis-Chalmers WD Operating Instructions And Repair Parts Illustrations

STARTER - The starter very seldom causes dif-
ficulty, however, if it fails to turn the engine
properly with a fully charged battery, check
all connections making sure they are clean
and tight.
If difficulty is experienced with the starting
motor, any one of the following may be the
c a u s e :
1. Exhausted battery.
2. Broken or loose wires.
3. Loose or corroded battery terminals.
4. Starter switch making poor contact.
GENERATOR - The generator charging rate is
controlled by a resistance unit built into the
light switch. This resistance unit limits the
amount of current allowed to flow through the
field coils of the generator.
The tractor is shipped with the field wire on
the generator disconnected. This wire must
be connected in order to complete the circuit.
If the battery is removed and the engine must
be operated without the battery in place,
disconnect the field wire to prevent damage to
the generator.
The generator very seldom causes any dif-
ficulty, however, if it does it is usually caused
by a dirty or oily commutator. To clean
remove the band over the brushes. Use grade
"00" sandpaper, With engine running hold the
sandpaper against the commutator.
use emery cloth as emery will cause short
circuiting,
CUTOUT RELAY - The cutout relay is mounted
on the top of the generator and provides an
'automatic switch for closing the generator
circuit. If the points in the cutout fail to
close, the ammeter will remain at zero. Do
, not operate the tractor in this condition as
damage to the generator will result.
Do not
If the points' fail to open when the engine is
stopped, the ammeter will show "discharge".
Disconnect the ,battery ground cable until the
difficulty is, corrected.
For best results, remove the generator and
have it checked by an authorized service
station.
