Voltage Regulators Burning Out on 14hp Kohler

Recently got rid of my model 70 and bought a 1450...it was clean and overall restored nicely.

After running/mowing twice it failed to start without a jump....then, it wouldn't hold a charge. Tested out to be the voltage regulator. Guy I got the tractor from is very nice and actually gave me a new VR (saving me $60).

Installed the new voltage regulator and after less than an hour the battery is discharging.

Voltage regulator is reading 30v across the 2 AC terminals but no voltage on the center pin.

Prior to the rectifier going bad I was getting readings that were all over the place at the voltage regulator.

I found multiple loose connectors going to the coil/condenser and the harness was melted.

I have tightened all the connections and added a ground from the VR to the chassis..... Any thoughts about what else could be causing this? I hate to keep experimenting with $60 voltage regulators.

I appreciate any 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.
