Default GT3200 wont turn off with new switch

My future father in law has a GT3200 that he loves and recently the key stopped working. I pulled the switch and opened it up to find some melted plastic and crud. Ordered a new Stens switch and it starts up fine, but will not shut off with the key now.

Was thinking the switch grounded the coil, but not finding a wire from the switch to the coil. Orange/white off "S" goes to the Brake switch which leads to an Orange/Black that leads to the PTO switch which leads to the orange/white to the solenoid.

He has mentioned some issues with the PTO switch not engaging as well intermittently so this all may be tying together now.

Thinking it may be a bad ignition switch I ordered a replacement. Any other ideas where to check? Hate to just start ordering a PTO switch as well as I don't want to just throw parts at it.

Need to see if I can follow the wiring along from the brake switch to the pto and then to the solenoid... Wanted to check with others.

Thanks!

Assuming you have the correct switch, with the key in off position the magneto gets grounded thru contacts M and G.
Pull the plug off the switch and check to see if you have ground on the G contact of the plug.
You might first check the 25 amp fuse that appears to provide the ground connection to the switch and also the PTO.

Thank you Ironman!!

Concentrating on the wiring too long I completely disregarded the key switch diagram at the bottom...

Going to test this switch to see if it connects the 3 listed.

Picked up a Stens Delta Ignition Switch 430-220 which crossed reference the same as the cub # and it has the same listed pinouts.

This is the ignition switch that is called out on the Cub parts site for a GT3200

925-06119C
IGNITION MODULE SWITCH RMC (MAN PTO BLK)
This part replaces 725-04227.

Many times the "Will fit look a like's" are wired differently internally and they don't work.

I confirmed that the Stens switch is the same replacement..

https://www.stens.com/430-220-ignition-switch

Also confirmed that is is not a switch issue as they are all connected when the switch is in the off position.

So now for a lot of fun tracing wires.....

Do you have a constant steady ground on the green wire of the plug that goes on the "G" terminal of the switch??

Will check that first, unfortunately the tractor is not at my house.. Going to pick it up next time I am there so I can troubleshoot easier. Thank you both for all of your input so far.

Confirmed that there is no ground at the green wire for the switch so I will pick it up this weekend and dig into it.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
