Kohler Pump-What does everything do?

I have one of these that works (sort of; see my post https://www.electro-tech-online.com/threads/kohler-whirlpool-tub-pump-73572.144498/)
and may be able to help if you're still interested after 3 years!!
If you're not AND you still have the pump, I'd be interested in buying it for parts.
Thanx,
emmette
