S250 Bobcat Loader
PM-21 Operation & Maintenance Manual
ELECTRICAL SYSTEM
Description
Figure PM-36
The loader has a 12 volt, negative ground alternator
charging system. The electrical system is protected by
fuses located in the cab on the steering control panel,
and a 100 amp master fuse [Figure PM-36] in the engine
compartment on the left side of the engine, under the air
cleaner. The fuses will protect the electrical system when
there is an electrical overload. The reason for the
overload must be found before staring the engine again.
Cleaning Battery and Terminals
Figure PM-37
The battery cables must be clean and tight
[Figure PM-37]. Check electrolyte level in the battery.
Add distilled water as needed. Remove acid or corrosion
from battery and cables with sodium bicarbonate (baking
soda) and water solution.
Put Battery Saver (6664458) or grease on the battery
terminals and cable ends to prevent corrosion.
