Andrew,
What Brett said .......

It wasn't quite clear to me that you were describing the test results of a bad solenoid. Based on your comments, it seems like the relay is pulling in as it should when you turn the key to start but it isn't dropping out when you turn the key off. Removing a wire from the coil (small wire ) and it really doesn't matter which one as either will break the coil circuit and cause the relay to drop out. If this is what is happening, then it appears to me that the relay is working. If the relay (solenoid) doesn't drop out when the small coil wire is removed then yes it would be "sticking" or stuck contacts.  It is also possible for this solenoid to sound like it's dropping out "clunk" but the contacts remain closed (large contacts still showing continuity)

Remote troubleshooting can be difficult, a good volt meter and a accurate wiring diagram would get you to the problem rather quickly. 🙂

I was thinking the same thing but did not know for sure.

If red 103 is supposed to power up the solenoid and doesn't should I leave that one off the post if the problem persist?

I'll post as soon as I install the Solenoid.

 Thanks Too All

Yes I understand Remote is hard but thanks for trying,

I understand your thinking about the function of the solenoid, So if that thinking is correct I must have a feed back keeping the solenoid energized, Taking 233 (left post) loose breaks the ground and it drops, so if the problem persist I may remove the small post wires (on the right post) one at a time and maybe I can get a lead on where the feedback is coming from.

I Surely Appreciate The Help.    And We Will Get To The Bottom Of This..

I thought the problem was that it didn't turn off when the key turned off (i.e. solenoid stayed energized) rather than not providing 12 VDC positive when the key turned on.

I'm sorry if I confused you,

 Problem is engine not shutting down when the key is turned off,

Looking forward, to what  if when the new solenoid in installed the problem persist,

Justin's comment on #25 got me thinking, There just might be feed back on the small post that's keeping it energized,

Hopefully I'll know soon if it's the solenoids

Thanks and Enjoy your travels

Mission Accomplished

Surprisingly Enough Problem Solved,

Solenoid was bad.

Thanks to all that helped and watched,

I'm Grateful For The Help

This is the value of the members/Forum as there is a lot of experience that can remote trouble shoot so you have some direction to go. A few of us have been in your shoes before. Glad you are on the road again.
