Finally, it's off
. Got a bunch of long sockets, 15/16, 1" 1/16" 1 1/8". Cut them down so the socket part was whole but the rest of the socket was cut down so I could fit it under the engine manifold. When trying to get the socket on the switch it would hit the engine manifold and not sit on the switch straight. Tried all the sizes, the 1 1/16" fit but would slip a bit so figured the switch might be metric.
Ended up finding a standard size 26mm socket, couldn't find a deep socket. I was worried the front part of the switch would stick too far into the socket and prevent the ratchet handle from attaching so I cut down the 1" deep socket and welded it too the 26mm socket. Tried it out on Sunday and worked like a charm. I was still only able to turn the ratchet about 1/4 way before the socket would jam against the bottom of the engine manifold. But turning it 1/4 turn, then removing and repositioning, I was able to get it off pretty quickly.
Replaced the switch with a Kubota 15841-39010 which seems to be the standard replacement switch. This switch is 15/16". Still had to use my deep 15/16" socket that I had to cut down to avoid the engine manifold but it went in smooth. I might have been able to get a short 15/16" socket with and extension on it to work but I didn't have on with me.
Big thanks to KWKloeber for all his help in my initial wiring confusion and then helping me trouble shoot the switch as the ultimate cause.
First picture is the old switch in the engine block. Second picture is the old switch removed and the cut down/welded 26mm socket. The 15/16" socket was cut down the same way.
