Re: (ET) FIXED! - E12 had lost power, field voltage

Thanks guys,
Well this list has come through again!  You pointed me to the Diode/Varistor assembly after correctly diagnosing the loss of field voltage to the drive motor.  I was examining and testing all the diodes with my neighbor when he noticed one of the wires leading to the assembly was bad.  It had its insulation stripped half off for about a 3 and a half inch length.  That turned out to be the problem.
    I covered the bare wire, put the motor back on and was finally able to get my lawn mowed!
This list is invaluable!
Thanks so much for all the advice,
Richard "Zack" Zachary

      With the control system your tractor has, the first and prime suspect for low/ no field voltage is the Diode/ Varistor assembly, located on the 'passengers' ' side of the Relay Panel, that rolls down 'under the hood'. I secure mine with bolts that have wing nuts affixed to them, for just such an occasion. {My daily driver is an E 20 CA. }
         If you find that those sixties vintage silicon diodes have evaporated, do not hesitate to go to RadioShack®, and buy some five ampere or larger replacements. Drill the holes out if you have to, or fab up your own board.
      It will outlast the OEM by a large margin.

Here are the model number and motor numbers.
Tractor model# 26AE12CA  serial # FP22038
with drive motor model# 5BC E56 KB5 with date code: FGN
If you can tell me exactly what to check for, I would greatly appreciate it.
There are two wire sets, attached to the motor besides the large main wires.  One looks like it has two wires in it and the other four wires.
Thanks so much for your help,

    It depends on which model of 12 you have.It would be a grand idea to
include the data plate model number whenever making a trouble post. It makes
puzzling out which wiring diagram to use much easier.

Use the 200 ohm setting, 'spect I could check my "12" and see what it
reads.  I wonder about the comments about "field", i thought the 12 used
a permanent magnet motor, guess I'll have to look.
