Did that once- blew the huge fuse, like 200amp. Was about $30 from AGCO.

A close friend of our family almost lost his eyesight from using a lighter to see a bats +/- to jump a car late one night.
Said that battery exploded in his face as soon as his lighter got near it & they picked small pieces of plastic out of his face and both his eyes for hours at the hospital. Very lucky man.
Any spark can make one explode and why its recommended we place the last clamp on the engine itself & not on the battery. I strongly adhere to doing that since his accident. That one certainly had to hurt.
Sort of makes me want to look the other way when I hook one up now but thats kinda whimpy so I put my face real close and smile to feel tougher.

John Deere are well known for anticipating a reversed battery by owner and often provide special diodes to try and limit the damage.
However, should there be diode(s) as part of a safety design, these can fail shorted and this could be why even when the battery is properly connected you still have a short.
If you have a wiring diagram you could post I will review it and comment further.
I have attached photos of one example from another brand.

On some JD models with a number of safety diodes JD puts them into a block that looks like a relay.
Post a wiring diagram. Dont continue to power things up and further destroy insulation.
