This is a industry standard, but I have encountered a few red main ground cables on IH and early CCC Cubs. Why they did that is beyond me.

The switch is correct and diode is correct....
The V/R takes a/c input voltage voltage produced by the engines alternator and changes it to d/c output voltage to keep the battery charged.
The a/c goes in on the two yellow wires at approximately 35 volts.
The d/c comes out on the red wire ideally 13-14 volts.

So, disconnect the red lead from the V/R.
Get out you DVOM, set your function switch to measure DC voltage (200 volt range) and connect the DVOM red lead to the red wire coming out of the V/R.
Connect the DVOM black lead to battery neg. terminal or a good clean ground on the engine.

Start your engine. Do you see any voltage on the meter.

Sounds to me like a shorted regulator. Do a resistance check from the output of the regulator to ground.

Thank you everyone for all your help, the final fix was to replace the regulator, I had one off of a spare engine. I finally get the cut some of my lawn LOL. You guys are a lifesaver.

Going to order one, may need help with the wiring.

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.
