Get your ohm
meter out . Between one pair of wires, expect less than 20 ohms . That is the
field leads. Check the next pair. Expect little or no resistance. Those wires
are connected to the Klixon® thermal limiter that's in the field windings. These
are connected in series with everything else in the RTN circuit for the traction
motor. It's another layer of protection to prevent an expensive melt down, and
is well worth keeping .
What model
is your E-20 ? If need be, I can look up the wire numbers if you don't have
the Homeowner's Service Manual. :)

Subject: (ET) Motor Field wires.
I am in the process of installing
the Alltrax controller on my E-20 tractor and have a question about the field
motor connections. My tractor has 4 wires coming out of the main motor
section with a 4 pin (kind a like a computer power connector) plug on
it. It appears that 2 of the wires may have been connected to the brake
switch which has long since been removed from this tractor. I presume
the remaining 2 are the actual field leads as I can place a meter on them and
have continuity across them. Is this a common wiring for the filed
connector plug? The alltrax schematic only shows 2 leads from the
motor. Any help on this would be greatly appreciated.
Thanks,
Bob K.
