2021 Ck2610se wire issue

[Rlinneman]

My tractor won’t start wants to crank over just won’t and when key is turned there is a snap or pop sound from the fuse box area obviously that’s where issue is. Checked all the fuses and made sure they were pushed in all the way. Everything is in neutral, pto off, seat switch connected and I’m in seat, brake on, brand new battery. Now with all that said a mouse got into my roof and chewed a bunch of my wires up there, would that be the cause of my issues? They’re for the ac and radio so don’t think that could cause it but if it’s all connected somehow . The snap sound is coming from around the fuel solenoid could that be it?
Any thoughts would be greatly appreciated
