Welding Precaution
WARNING
It is very important that correct procedures be followed when welding anything connected to the
windrower. If procedures are not followed, it could result in severe damage to sensitive, expensive
electronics. Even if complete failure of a module doesn
’
t happen immediately, it is impossible to know
what effect high current could have with regard to future malfunctions or shorter lifespan.
Due to the number of connectors, components to be welded should be removed from the windrower whenever
possible rather than welded in place. When work needs to be completed on a header, disconnect the header
completely from the windrower before welding. These same guidelines apply to plasma cutting, or any other high
current electrical operation performed on the machine.
The following items need to be disconnected:

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

Figure 1.13: Master Controller
•
Master controller (A)
Four connectors: P231, P232, P233, and P234
Location: Behind cab, near header lift/fan manifold
To disconnect the connectors, press the two outer tabs,
and pull the connector away from master controller.
IMPORTANT:
When reconnecting these connectors, double-check 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.
