Mahindra 1526 won't stay running!

[Sierra1time]

I own a Mahindra 1526 2018 model. Recently the positive battery terminal took a dump and it was replaced. Ran fine after that. Put it up and about three days later went to crank it and when I turned the key, the usual pre-start dash lights did not come on. turned the key and it started but the minute i released the key to go from the start position to the run position, you can hear the fuel shut off solenoid click and the tractor dies. Checked all the normal safety switches and they are good. Checked the ignition switch with multimeter and it seems to be getting 12.75 volts when key turns to start and 12.75 to the constants. double checked the battery terminals and all the fuses. Cant see any wires that are loose or broken. not sure what else to do. Guy at the dealer says it may be the fuel solenoid but that wouldn't explain the dash lights. If I keep the key turned to the start position, the tractor continues to run as normal with no dash lights but when I release it...dead. wanted to leave this up in case it helps someone else...but here was the solution:
I called my wife's uncle (awesome diesel mechanic but he works out of town most of the time) and he came and took a look. Evidently keeping my tractor in the barn isn't enough, because a mouse had chewed a wire under the dash from the ignition, to the engine! Soldered the wire and bam...I'm back in business! Set out some traps and caught a few of the little beggars too. I think I could have saved some time as well by checking continuity in the wires coming from the ignition. Pulling the dash wasn't that hard either and there a lot of fuses under there. Good luck, stay up wind, and keep both eyes open!

Bad key switch or loose wire on run terminal? Hold circuit on solenoid maybe bad. Some of these solenoids have a pull in coil and a hold coil. The pull in coil is the bigger one and it pulls the solenoid to open the fuel. The hold solenoid holds the valve open to allow the engine to run.

Go back to your most recent repair. Clean both battery terminals and associated connectors. Replace both connectors on the battery and tighten securely. If you can wiggle or turn them they are not secure. Clean and tighten where cable attaches to frame. What kind of repair did you do? Did you replace the connector or the whole cable? If you merely replaced the connector with the clamp on type it's possible the wire was not clean enough or you did not tighten the connector on the wire adequately. It's possible your run solenoid has two coils. One is for starting the tractor and the other is for running. If the run coil has gone open that would allow the tractor to start but not continue running.

Thanks guys! I called my wife's uncle yesterday (awesome diesel mechanic but he works out of town most of the time) and he came and took a look.
