Just after the first snow this season my NH TC30 acted dead. Lights worked and battery was well charged. After a lot of searching here and a few calls to a NH dealer, the suspicion fell on a black little box labelled "SAFETY CONTROLLER". Nobody near me seemed to have any way of checking the function of that little box, about the size of a deck of cards, and a new one cost 450 bucks, with no way of returning it if it should turn out to be a different problem.
Two pieces of wire solved the problem. One from key switch to starter solenoid and one from key switch to solenoid fuel shut off at the injection pump, and now all is well. The tractor now works just like older tractors did without all the government mandated safety crap. The only thing that doesn't work, is the dash light for heater plugs, but I know enough not to fry them.
