No power at all

Looking for any help possible. Have an old MF-50 in the woods behind my house. Started to tinker with it a few weeks ago. I changed all the fluids, replaced wiring, put new ignition switches and new battery. I’m not getting anything when I attempt to start it. Any ideas out there?

Engine or starter stuck?
Get your ohm meter and check for current to the starter and good ground. One bad electrical connection could be the cause of your problem and those to the starter and ground could be bad. If all of that is ok, pull the starter off, lay it on the ground, and connect it directly to a good battery. It should spin, freely and fast, if good. Remember to connect plus and negative cables with the correct polarity. That is where I would start. Also don't forget the connections from the switch.

Agreed. If it was sitting in the field it might not have a good ground. You can always bypass the starter and see if that works but the Ohm meter is the way to go.
I’ve checked all the connections with an OHM meter, and everything seems to be OK. I have the starter out of the tractor and I’m going to test that. This may sound like a stupid question, but I’m new to tractors. Should there be two connections to the starter or just one when it is installed? I’m used to standard automotive starters to have a built-in solenoid and multiple connection points.
I have had no experience with that tractor. So I ask does it have a 6 or 12 electrical system. If 6 volt it should be positive to ground, near the starter, and negative from battery to the starter or solenoid. If a 12 v system negative to ground and positive to starter. Some pics might help us.

It’s a 12 volt. I found a PDF wiring diagram and it looks like everything is correct. Just waiting out some inclement weather here and will head back out. I appreciate your advice.
