ALTERNATOR
The alternator supplies electrical current to charge the
battery and power the electronic controls. The built-in
regulator controls the voltage output.
If for any reason the wires must be disconnected from
the alternator, mark them before removal so that they
can be properly reconnected later.

Figure 5-6. Alternator
Follow the following precautions to
prevent damage to the alternator and/or
regulator:
• An alternator is never to be polarized. Never
ground any alternator terminals or circuits.
• Always disconnect the battery before
disconnecting or connecting the alternator.
• Never disconnect the alternator while it is
operating.
• Be certain electrical wiring is properly connected
before connecting the battery.
Cleaning and Tightening Battery
Terminal Connections/Terminals
Be certain that terminals and battery
posts are thoroughly cleaned and that
battery cable terminals are tight. Dirty
or loose connections can create high
electrical resistance and permit arcing,
which will quickly burn and pit terminals
and posts.
Keep the battery clean by cleaning excessive buildup.
To remove corrosion:
1.
Refer to Preparing Grader for Maintenance on
page 5-6 and park grader.
2. Unhook battery box locks on the battery
compartment and remove cover (Figure 5-7).
