Default Cub Cadet 128 starting issues

When I hook up the battery, the s/g starts cranking over, disconnect battery and it stops, also noticed that the amp gauge pegs to discharged side while it's cranking. I have replaced Ign switch, solenoid, and voltage regulator. I'm at a loss.

Sounds like something isn't wired correctly, here's a link to the wiring diagrams. I suggest you start by double checking it's wired correctly.

Agreed,

Also, Are you sure you got the correct ignition switch ? Is it an aftermarket switch?

Let's back up.....
Since you say that as soon as you hook the battery up, it starts cranking. That means previously, you had the battery hooked up and it didn't do this. What was the original problem that you set out to fix?

More than likely you wired the v-reg incorrectly when you hooked it up.

Or you have stuck contacts inside the V/R. All speculation until we have more info

Default Cub Cadet 128 starting issues

I am not sure if it's a new style, will look at it again tonight. When it's cranking I have battery voltage at the yellow wire at the s/g ??? The tractor has not ran since I purchased it this spring, the engine was bad so I replaced it. PO said it used to run but smoked. I have gone over the wiring with an ohm meter and load tested the wiring with a test light, all checked OK. Been a automotive tech for 40 years, the last 26 years at a GMC/ Buick dealership so wiring is not a problem for me. My thoughts are a stuck v/r. Will look into again tonight and triple check wiring diagram.

Well then I would have surely thought you could figure this out. Pretty simple system. If you suspect(ed) a stuck V/R, unhook it and see if it still does 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.
