Welcome to GTtalk Cdmj80. From your post I take it that the engine will not turn over. Since it is not yours have you checked and turned the engine over manually to make sure if it free? Next what is the voltage in the battery? Once those two things are checked I would start reading voltage from the starter back and see where you are loosing it. If you have 12 + volts at the starter then I would say you have a bad starter. If not start checking to see where you do have volts.
Quite a while back I was working on a bike that would not turn over. Checked everything but when I read voltage at the starter it was like 6 or 7 volt if that. What I found was corrosion in side the main hot cable coming off the battery.
I'm sure others will have ideas to share as well.

So as I understand battery is 12.01 VDC OK
Following the heavy battery (RED - positive) cable to the solenoid is 0 VDC - correct?
Voltage to the coil side (usually a smaller wire) of the solenoid is ? VDC when key turned to start.

I often find one or both battery cables corroded where they join the battery clamp. Also check the cleanliness of terminals and clamp.

Can you get a pic and post of the solenoid (3 or 4 wire hook up type). Can you hear (Clicking or humming noise) or feel the solenoid engage? If not then the coil is bad on the solenoid most likely or bad key switch. Also if the coil does make a noise and engages there should be 12 VDC on the other side of the solenoid (heavy cable to starter).

From what i read so far, you get no reaction from the ignition switch but if you hot wire the solenoid the engine turns over slowly. Are you positive that you have the exact replacement ignition switch for your model?
The cables may be corroded enough to not allow adequate amperage to flow to the starter.
The starter may need to be replaced/rebuilt.
Is it an overhead valve engine? The valve tolerances may need to be reset.
Hope you get it figured out quickly. Rick

there should be safety switches
for starting in netrual
it could can be bad.
a bad pto switch can also cause your problem

The key switch sounds like the problem, are you sure that the one wire is suppose to go there? I don't have a diagram, so double check where that goes. It is either the wire in the wrong spot or the wrong switch. Double check with a local JD dealer with a good support/service/parts. They are usually able to help with knowledge, correct diagrams, parts.

CD, Did you get the JD 111 problem resolved? if not, post what year it is & I'll put up some wiring diagrams. KE
