Do you have a wire to the 'R' or ignition post on the solenoid?
Or 2 wires to the 'S' terminal? (purple wire only there)

I'm pretty sure that you have already disconnected the wire(s) from the "S" terminal while the problem was occurring and that action did not cause the starter to quit turning. If so, this latest test of disconnecting the safety switch means nothing.

I have the one purple wire to the "S" side of the solenoid and the one yellow wire to the "R" side of the solenoid. Both of these wires were securely attached to the solenoid for this latest test.

Take the wire to the "R' terminal off (and tape up) then try it?

Wh y not take both wires off starter, R & S terminals and run 1 temp wire to the S terminal, if it stays engaged, one would think there is a Mechanical
Problem and not electrical. Whether it be in the starter or the drive engagement, not sure but worth the try. Or use somebody else starter and try.

Try a different make solenoid.. That’s what solve the problem for me in my tractor. The first two were the same make. Doing the same as your solenoid. I put the old one back in and no problem. Only thing, it was hit and miss if it would engage, so I knew the problem was in the solenoid’s that I bought. I was able to find a NOS,, and it has been problem free for over a year.

Default Yet another test update.

johnta1, I removed the yellow wire from the R terminal and taped it up. (Purple wire still connected to "S" terminal) starter still spins; quickly disconnected Neutral safety switch connector(two purple wires) from the neutral safety switch and starter still spins. So with no wiring (Effectively) connected to starter (other than the two red cables to battery and alt.) Where is the voltage coming from that keeps the solenoid engaged?? Could the second (New) solenoid be bad???

Start on page one and read through all my posts.

You can't see what's wrong.

You can test for what's wrong.

The switch in the solenoid cap is being mechanically held closed when the starter is turning the engine over.

Default Update

I have removed the new engine harness and shipped it back to the manufacturer in NJ who has agreed to take it apart and look for any potential issues that are causing the starter to not stop from spinning. I dont expect to hear back from them for about a week or so. I will let everyone know what they find out. Dave

The starter continuing to spin with purple wire disconnected from the S terminal IS NOT an electrical problem.

It's a clearance problem inside the starter. It will bench test fine but hang up when it's under a load turning the engine.. The switch in the solenoid cap is being held closed by mechanical force.

Not right but the starter should disengage when the engine fires up.

Hook B+ cable only to it now and jump S to make it spin. Try it and see if that helps you understand what I'm talking about.

Wanting and trying to help here

Dave, I still think you are chasing ghosts in the wiring. Halloween is coming and I hope you get lucky with the harness. While you are waiting try post 114. That will tell about the wiring. If it still acts up when you get the harness back on I would still be happy to look at your starter or see you try a different one.

Dave,
The test you performed in post 108 effectively eliminates any electrical problem.

You removed the wire from the R terminal at the sol, & the problem remained. So that removes this wire as the culprit.

You also removed the purple S wire, eliminating it as the problem source.

That only leaves a mechanical problem such as mesh, or an internal starter problem.

Thanks again Geoff and everyone else. Received the Main engine harness back from American Autowire after they disected it. They said the yellow resistance wire was partially melted so the replaced that wire and said everything else is fine. Reinstalled everything and now when I turn the key, nothing happens at all. I do have voltage to the purple wire at the neutral safety switch. With key in run position, I have no voltage at the "S" terminal/purple wire at the solenoid post. Had assistant turn key to the start position and still no voltage at all at the "S" terminal/purple wire. This is getting real annoying now! I will call American Autowire on Monday to get there opinion unless anyone here has a thought?

I'd put a push button on the purple wire...

4 speed cars have a clutch safety switch, for safe cranking, that works when you push the clutch pedal down. Stick shift does have backup lights on the steering column.

Automatic cars have a neutral safety/backup light switch on the steering column.

Purple wires to either one should only be hot when ignition switch is turned all the way forward to crank position.

Yellow wire had gotten too hot.. Point contacts will probably be burned up.

Have you changed anything besides the R&R of the engine harness?

Is this the wiring from the firewall connectors on the firewall to all the 'stuff' under the hood?
Does the purple wire have 12 volts inside the passenger compartment to the firewall connector?
None on the engine side?
Possibly they have wired the wrong pins up? (on connectors)
