1.8 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 windrower before welding. These same guidelines apply to plasma cutting, or any other high current
electrical operation performed on machine.
The following items need to be disconnected:
• Negative battery terminals (two connections) (A)
IMPORTANT:
Always disconnect the battery terminals
fi
rst, and
reconnect them last.
Figure 1.19: Negative Battery Terminals
• Master controller (four connectors: P231, P232, P233,
and P234) (A)
Location: Behind cab, near lift fan block
To disconnect the connectors, press on the two outer
tabs and pull connector away from module.
IMPORTANT:
When reconnecting these connectors,
double-check that the connectors are fully seated
into the module, 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.
