5.10 Electrical System
Refer to this section for information on maintaining the windrower’s battery, lights, and the circuit breaker and fuses.
5.10.1 Preventing Electrical System Damage
The windrower’s electrical system cab be damaged if the proper operating procedures are NOT followed.
Figure 5.120: Alternator
A - Negative Terminal B - Positive Terminal
To prevent damage to the electrical system, take the following
precautions:
• When connecting a booster battery to the windrower’s
battery, ensure that the leads are connected to the proper
terminals and grounding points.
• Do NOT short across the battery or the alternator terminals,
or allow the battery’s positive (+) cable or alternator wire to
become grounded.
• Ensure that the connections from the alternator to the
battery are correct before connecting the battery to the
windrower.
• When welding on any part of the machine, disconnect the
battery cables and alternator wire. For instructions, refer to
1.8 Welding Precautions, page 9.
• Always disconnect the battery’s ground cable when working
with the alternator or the regulator.
• Do NOT attempt to polarize the alternator or regulator.
• If wires are disconnected from the alternator, ensure that
terminals (A) and (B) are reconnected properly.
• Do NOT ground the alternator’s field terminal or the field.
• Do NOT connect or disconnect the alternator or the
regulator wires when the battery is connected or when the
alternator is operating.
• Always disconnect the battery’s connection to the
windrower when using a charger to charge the battery.
• Ensure that all cables are securely connected before
operating the engine.
• To prevent damage to the windrower’s circuitry, disconnect
the negative battery terminal when replacing an electronic
control module. Additionally, when handling an electronic
control module, avoid touching the connector pins directly.
