Default PTO Clutch Troubleshoot

Good morning good people. I have read some great info on this but am looking for some assistance of where to go from here. Here's what i know (think I know)...
1. Cub Cadet LT1045 (2005) - 500 hours
2. PTO won't engage
3. PTO clutch does engage (click) in a direct from battery connection (the current installed battery)
4. The PTO switch seems to show proper connectivity when on/off
5. With key on, PTO engaged, someone on the seat - I am getting 12.2 volts in the last connection - at the clutch pigtail (black on ground, red on either of 2 wires going into clutch).
6. PTO Clutch wires show 3.2 on resistance through the clutch

This winter I was not able to start the mower and jumped it with car jumper to start it. I had some trouble getting it to start even with jumper. After it started it stopped after a few seconds. I found the 20amp fuse was broken - actually melted. After battery was charged, i had looked around wiring a bit, saw nothing, went through 4 more fuses trying to start. Now it is running just fine, used it in the snow a fair amount - fuse is not having any problem. Just no PTO.

Thoughts? Thank you!

Joe

I can normally figure out a wiring diagram but I don't understand the one for the 1045. I'll just toss this one out, Cub for what ever reason on the later tractors that I've had the misfortune to work on is switching the ground to the PTO rather than the hot side so they have power to the PTO as long as it's running but the PTO doesn't engage until the switch completes the ground. I can e-mail the diagram to you, PM me your e-mail address and I'll send it. I found it with a Google search.

Thank you Sam. I am going to make sure there is not a safety swith issue and my connections are all clean. On the grounding - is it just a matter of going to each ground and assuring they are well connectedi and wire looks ok?

Check every thing. I sent you the diagram. I've never worked on one so I'm not much help.

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.
