Tz25da start issues

[SuperBeetle]

All dash lights will illuminate except glow plug. Tractor will not start. Have checked all the safety switches...all ohm out correctly. I have not by-passed any switches. Did manage to get the tractor starter recently, but have no clue what course of action led to tractor starting. Now I am back to no glow plug light...no starter engaging. Headlights works...battery fully charged. I will see if I can by pass the neutral switch...since that seems to be popular in all the chats concerning this issue. Would be nice to read those who on the past experienced the same problem, what was their resolution. Thank you for your response.

PTO is off? I’d start checking to see if voltage is getting to the starter solenoid.
If no, it’s in the safety interlocks, key switch, or whatever relays are in the upstream “low amp” side of the starting circuit.
If voltage does make it there, but starter solenoid doesn’t pick up, or it does and starter doesn’t turn over, it’s the solenoid, starter or “high amp” connection side of things. Example: A bad battery ground.
