Yesterday mu buddy and I put a pair of jumper cables on backwards from a truck to my z810 battery and I think the battery is still fine though I believe we fried the wiring harness or possibly the motherboard. Can anyone shed any light on my situation?
Wiring harness?

Post the model and serial numbers of the unit so we have some idea of what you are talking about. Our psychic powers are down, due to COVID-19, so we have no idea of which model of JD you have. We hate guessing, as it looks is a waste of everyone’s time.

Rivets, Do you need reading glasses too?
The op said it is a JD Z810(A).
To OP. Do you have any power? If not you may have just blew the main 20A fuse. Otherwise yes you could have blew the Vehicle Controller board but only testing will find the problem. Reverse connecting the battery can do a lot damage including blowing the voltage regulator and possible damaging both ignition coils.

I used to have one pot by now but I am a very limited intake of liquids and food due to stupid doctor refusing to put me back the BP med that worked. No explanation as to why he is refusing to it. I am currently hunting a doctor that will work with me on the problem.
SO I only had one this morning and no breakfast. Table legs are looking good enough to eat.
I current fight with a Z325A. Darn JD Parts is saying two different main air filters used. They gave the customer the wrong one of course.
It is a z810 john deere zero turn lawnmower
