Quite a perplexing issue. I have run out of ideas as to why this is happening. Not a new build. I fixed a busted X endstop. Then my main board died. Stealthburner LEDs no longer worked and hotend fan was always on. Replaced Mainboard now I have this issue.
Current Status:
Everything works except Z Endstop and Probe are always triggered. Probe LED is on and when it is close to the bed it turns off as it should.
What I have tried:

What I have tried:
- Replaced BTT SKR Mini E3 v3.0 (due to failed board before / Plausible new board is bad)
- Replaced Probe
- Replaced Toolhead PCB
- Continuity checked Probe Signal wire
- Confirmed BAT5 Diode is working correctly with multi-meter
- Checked if old Main Board has the same issue and it does
- Loaded old working config and confirmed same issue
- Double checked my printer.cfg settings
- Can you simply bridge GND and PC2 on the Z-Stop to manually trigger the Probe and Z Endstop? That would allow me to determine if the issue is with the board / config or wiring
- I noticed if I remove the Fan PCB from my 2-piece hartk1213 Toolhead Board the Probe looses power. Is this as intended or indicative of a wiring issue?
