Alternator Servicing
The alternator supplies electrical current for charging
the battery that provides electrical power to electronic
controls. The built-in regulator in the alternator controls
the voltage output. (Figure 5-20)
Figure 4-20. Alternator
If the wires must be disconnected from the alternator, be
sure to mark them for proper reconnection.
Use the following precautions to prevent damage to the
alternator for any maintenance performed:
• Always disconnect the battery before disconnecting
or connecting the alternator.
• An alternator should never be polarized. DO NOT
ground any alternator terminals or circuits.
• Never disconnect the alternator while the machine is
operating.
• Be certain the wiring is properly connected before
connecting the battery.
When replacing the battery, discard the old battery
properly. Before connecting the battery, be sure the
Master Disconnect switch is turned off. The switch
is located on the conveyor control panel left of the
operator. (Figure 5-19)
When servicing the electrical system
or welding on the machine, always turn the Master
Disconnect switch to the OFF position to disconnect
the ground strap from the battery to prevent damage
to the machine electrical system.

Be sure to keep the battery fully charged during cold
weather to keep it from freezing. Freezing weather has
little effect on a fully charged battery.
When connecting a booster battery, if necessary for
cold weather starting, connect one end of the rst
jumper cable to the positive (+) terminal of the dead
battery and the other end to the positive (+) terminal of
the booster battery. Connect one end of the second
jumper cable to the negative (-) terminal of the booster
battery and the other end to the frame of the machine
with the dead battery.
DO NOT attach the negative (-) cable
from the booster battery to the negative (-) post of
the dead battery because a spark could cause an
explosion.
