2020 Zetor M40SS won't start up

[0d3ll.frm]

I was using our 2020 Zetor M40SS yesterday, just moving it around the pasture. Parked it, went for lunch, then about an hour later went to start it up again and got absolutely nothing. No lights, no dash, no click, just dead. I checked the battery with a multimeter, and it's showing good voltage. I even tried jumping it with my truck, and still, zero power anywhere. It's like the main power isn't even making it into the system.

Any thoughts on what might be causing this? Fuse, relay, something more serious? Any common M40SS issues like this? I'd appreciate insights!

@0d3ll.frm I know tht you've checked the voltage and tried jumping it, but you also need to take a really close look at the battery connections and the ground cable.
A tiny bit of corrosion or a slightly loose bolt on the negative ground cable can be enough to completely kill the whole system. A good wiggle and a solid cleaning might be all it takes

That’s a good call from @CatKingpin. Also check the main fuse or fusible link near the battery since a blown one will make it feel completely dead like that. Let us know what you find, those M40SS gremlins are usually something simple.
