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
