Preventing Electrical System Damage
The windrower's electrical system can be damaged if the correct procedures are not followed when the windrower is
serviced.
To prevent electrical system damage, take the following
precautions:
• Carefully observe polarity when attaching booster battery.
• Do NOT short across battery or alternator terminals or allow
battery positive (+) cable (B) or alternator wire to become
grounded.
• Be sure alternator connections are correct before
connecting the cables to the battery.
• When welding on any part of the machine, disconnect
battery cables. For instructions, refer to
Precautions, page
10.
• Always disconnect battery ground cables when working with
the alternator or regulator.
• Never attempt to polarize an alternator or a regulator.
• If wires are disconnected from the alternator, refer to
Figure
5.35, page 382
to ensure proper connection.
• Never ground the alternator field terminal or field.
• Never connect or disconnect alternator or regulator wires
with battery connected or alternator operating.
• Always disconnect cables from the battery when using a
charger to charge battery in windrower.
• Ensure all cables are securely connected before operating
engine.
• To avoid damage to circuit boards by static electricity,
disconnect negative battery terminals when replacing
electronic control modules. Furthermore, when handling
electronic control modules, avoid touching the connector
pins directly.
