Can anyone provide a pdf or other scan of the TC30 electrical diagram - particularly the chain of safety switches?

Most times I want to start the tractor, sounds like the starter solenoid only partly engages. A soft click, but no starter. After a minute or so fiddling with the gear shift lever, in and out of the two 'neutral' positions, or sometimes stomping on the foot brake, the tractor will start.

I believe there is just too much voltage loss through the train of safety switches (seat, brake, two pto switches, shift in neutral). A circuit diagram would be a great help trying to chase this down.

Been this way for a couple of years now, and it's really starting to bug me. When it first began happening, I assumed the battery was getting old. Put a charger on the battery, and the tractor started right up. Went and bought a new battery, but same problem continued.

As we used to say when I was an Air Force jet instructor pilot: "Give the students books, and they just eat the covers."

Shame on me.

But if anyone has any better information, I'll take that too.

Shu,
I also have a TC30 and once in a while I have that problem. All I do is move my speed control lever a little and off it goes. However, after blowing snow in the winter and parking in the barn the safety switches freeze and it's a no go until I take a heater out and thaw them all out. I solved that problem by parking it in a heated garage. When I find my manual, I'll see if there is a diagram in it of what your looking for.

Check for corrosion in the bullet connectors at the various PTO and transmission neutral safety switches.
