CHARGING AND
ELECTRICAL SYSTEMS
Alternator
An alternator is used to c har'ge battery. Alternator
charging system normally requires no service other
than periodically checking all exposed wiring and
electrical connections on tractor are clean, tight and
in good condition.
Proper polarity is critical with an alternator
equi pped charging s ystem. Always disconnect
battery ground cable (negat ive) before working
on any part of the electrical system. Verify all
components are connected correctly before re ..
connecting ground cable (negative) or damage
to a lternator system components will result.
Never run engine if battery is removed, or if
battery is not connected to charging system.
Serious damage to charging s ysem components
may result.
Main Fuse
A 25 amp (416, 4 17-Models) or a 15 amp (200-
Series
&
308, 3 10, 3 12, 414-Models) automotive type
ATO or ACT fuse is used to protect main circuit of
electrical system. Fuse locations are shown below.

Light Circuit and Fuse
200'Series; 308, 3 10, ' 3 12, 414 Models:
Electrical
system has a separate circuit for operati ng lights.
Alternator output for this circuit is ALTERNATING CUR
RENT (A.C.). For this reason lights will not operate
without engine running. A fuse is not used in this
light circuit. Never interconnect A.C. lighf circuit and
D.C. battery circuit as this may result in serious dam
age to charging system.
416, 417-Models:
light circuit is powered by bat
tery. lights will operate when ignition switch is in Run
position. A 15 amp a utomotive type ATO or ATe fuse
is part of light circuit. Fuse holder is next to main
fuse holde·r (See preceding IIMain fusell).
Voltmeter and Hour Meter Fuse
200 .. Series:
Meter circuits
are protected
by main fuse
(See preceding liMa in Fusell).
3 10, 3 12, 414-Models:
Meter circuits are protected
by a 5 amp automotive type ATO or ATC fuse located
next to main fuse (See preceding liMa in Fusell).
416, 417-Models:
Meter circuits are protected by
light circuit 15 amp auomotive type ATO or ATe fuse
located next to main fuse (See preceding "Main Fuse").
Electric Lift Fuse
417-8 Model:
lift circuit is protected by a 20 amp
automotive type ATO or ATe fuse located next to light
circuit fuse. (See preceding I/Main Fuse").
