Default Coil is hot
Having an issue with the KT17 in my 782. I replaced my battery and when I connected the cable there was a small spark indicating something is drawing some power. Amp gauge also shows a discharge. But about 30 minutes later I placed my hand on the coil and found it to be hot.

So I am hoping someone has seen something like this and give me a direction to go.

Thanks

Well
Nobody ...
So I went to the troubleshooting and service info area and found the manuals you all posted here. Thank you. A terrific source for answers.
I tested the coil and directed and the primary winding checked to spec but the secondary checked "open". As did the plug wires. I don't understand why that would be.
Condenser also checked out.
Points are clean.
I checked compression and had 90 psi on both cylinders. Not sure if this is a good number but it doesn't seem too low or uneven. I can check later after some run time to see if there is any change.
So after a lot of starter fluid and cranking we are now up and running. I've adjusted the main and idle screws to my satisfaction.

So after all that I did notice something while trying to get started. I had a tendency to leave the key in the run position after a failed cranking. So I'm leaning toward the "hot coil" issue to me leaving the key on.

Any seconds to that?

I second that motion, don't leave the key in the run position, as the points, when closed will heat up the coil and ruin it....

#90 compression is just fine,
These double breasted opposed twins are low compression engines.

Eegads !! It's worse than I thought! I'll be more careful in the future ...

Thank you for the kind encouragement.

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.
