NH TC30 electrically dead

That,s why to properly check a battery you need to do a load test on it. Resting voltage doesn,t mean much.

I know on my old Case IH, which was also a New Holland build, there was a fuse in a location that was obscure and hard to find.

The only way I found it was looking at a schematic online. It's a main fuse right around the starter, kills everything. It was also kind of hard to get to.

I highly doubt it is the battery it would probably give you something,, a click a flicker of light, if just a weak battery.

As already mentioned, I would try the connections, find a schematic for the all the fuses, and take the battery to a Napa and have them check it

Since you were using the PTO that sounds like a strong possibility that a switch is not making connection.

Don't underestimate the effect of resistance in a circuit. I have a small fishing boat with a deep cycle battery powering the running lights. What possibly could stop a big, bad deep cycle battery from lighting the lamps? Oddly enough, I was getting good voltage at the terminals, but there was not enough current to light the bulbs. I hosed all the connections with CRC 2-26 and bang the lights came on! I then went again and cleaned them, lubed with silicone grease for protection and have not had a problem since.

True, 12.6V (or 12.5V) doesn’t tell you the amount of available charge, but it tells that all cells are 2.1V and available, that is, it’s not resting at 10.5 volts with a shorted cell.
