Is it a major rewire to move to
the later contactors (6 terminals)? Or is it just a matter of connecting
the old wires up to the new contactors and just removing a wire or 2 that is
not needed anymore? From: RJ Kanary

Yes. The later contactors make for a much simpler arrangement.If you
wanted to try to fix what you have as an exercise all the individual pieces are
functionally identical.Your assumption about 1F &2F being OK is correct.
The other contactors that bypass the armature resistors are just swell if you
have three forward traction motor speeds. :) { In Forward. You are only
allowed two speeds in Reverse.}
If one of these were to fail open such as your reversing contactors, you
would be missing a speed change but the tractor would still move.
Each reversing coil and contact unit is a separate entity.All do the same
function when energized, and the mechanical interlock[ Those little pins that
you better not lose if you decide to try to repair them. :( ] between
opposing contactors assures that nothing bad can happen due to a set on
contacts being closed when it shouldn't be. RJ |
