YTH2448 interlock

[Don'tPanik]

Hello,

I have a YTH2448 that starts fine if I jump from the battery to the starter but will not start from the key. I have verified the seat interlock, I've replaced the brake interlock and the ignition switch. The PTO works fine and has been replaced a couple of seasons ago. What else can be keeping it from starting with the key?
TIA
