Welding Precaution
Understand these critical precautions before attempting to weld anything on the windrower.
IMPORTANT:
If the procedures below are not followed, damage to the windrower
’
s electronic components may result. Some
components may only be partially damaged, which would result in some electrical components failing in an intermittent
way. Such faults are very difficult to diagnose reliably.
The windrower is equipped with several sensitive electronic components. Therefore, components to be welded should be
removed from the windrower whenever possible rather than welded in place.
When welding needs to be performed on a header, disconnect the header completely from the windrower before
beginning. These same guidelines apply to plasma cutting, or any other high-current electrical operation performed on the
machine.
IMPORTANT:
Ensure that the windrower is parked on a level surface, the ignition is turned off, and the key is removed before
disconnecting anything.
The following items need to be disconnected:

•
Negative battery terminals (A) (two connections)
IMPORTANT:
Always disconnect the battery terminals first, and reconnect
them last.

Master controller (A)
Four connectors: P231, P232, P233, and P234
Location: Behind the cab, near the header lift/fan manifold
To disconnect the connectors, press the two outer tabs, and
pull the connector away from the master controller.
IMPORTANT:
When reconnecting these connectors, ensure that the
connectors are fully seated into the master controller, and
that the two locking tabs on each end of all four connectors
have popped outward. If the tabs are not popped outward,
the connector is not fully seated.
IMPORTANT:
Do
NOT
power up or operate the windrower until these
connectors are locked into place.
