and that the negative terminal is connected to
ground. Reverse polarity will destroy the recti-
fier diodes in the alternator.
If the charge indicator warning light indicates that
the alternator is not charging the battery, check the
fan belt and the wiring connections. If these are
satisfactory and the warning light continues to in-
dicate no charge, consult your SHIBAURA Tractor
Dealer.
FUSES
Fuse Blocks
The two main fuse blocks, Figure 71, are located
on the right-hand side of the engine compartment
fire wall adjacent to the air cleaner. Two additional
fuse blocks, Figure 72, are attached to the head-
light support bracket inside the engine hood.
When viewed from front to rear, the upper and low-
er fuse blocks contain the following fuses:
Figure 71 - Main Fuse Blocks
Figure 72 - Headlight Fuse Blocks
Upper Fuse Block - Figure 71
Fuse Size Circuit Protected
① 20 amp. Headlights, Parking lights
Instrument panel lights
② 15 amp. Indicators, Hazard lights
③ 10 amp. Brake lights, Horn
Lower Fuse Block - Figure 71
Fuse Size Circuit Protected
④ 5 amp. Warning lights, Gauges,
H.S.T. speed control
⑤ 5 amp. Engine fuel solenoid
Headlight Fuse Block - Figure 72
Fuse Size Circuit Protected
① 75 amp. Headlight - Low Beam
② 75 amp. Headlight - High Beam
NOTE：
：：
：Before replacing a fuse ensure all electrical
circuits are switched off. Always replace blown
fuses with the size specified for that circuit.
Fusible Link
A fusible link wire, Figure 73, is used to protect the
tractor’s entire electrical system. If too much am-
perage passes through this wire it will melt down so
that it will no longer allow circuit to pass (similar to
the way a fuse works). The fusible link wire is a red
wire that goes from the starter terminal to a con-
nector that links into the main wiring harness.
To replace the fusible link wire:
1. Disconnect the negative battery cable from the
battery.
2. Unplug the connector linking the wire to the
main wiring harness.
3. Remove the old fusible link wire from the starter
terminal.
4. Replace the old fusible link wire with a new one,
first attaching to starter terminal, and then con-
necting into the main wire harness.
