At my wits 2Nd

OK, let's be very specific here. A 6 volt battery showing only 6.0 volts is a seriously undercharged battery, possibly because it has gone bad.

What is the exact voltage your meter tells you with one lead on each of the battery posts? Notice that a fully charged 6 volt battery should show 6.37 volts.

Volt meter can't get a good read right now, I'll probably take some time to clean the contacts with some scotchbrite later, battery charger I hooked it up to is saying 6.3-6.4, but it's a Canadian Tire charger so I'm not super confident in those numbers.

coil does not spark when hooked directly to the battery. and touching the frame of the tractor.

I think there is some confusion. What exactly do you mean by touching the frame of the tractor? For positive ground systems, the positive terminal of the battery should be connected to the tractor frame and the negative cable should be connected to the starter solenoid on an 8N or to the starter switch on a 2N or 9N. To bypass the wiring for the ignition you would run a wire from the negative post of the battery to the terminal on top of the ignition coil terminal. Then crank the tractor and see if there's any spark at the plugs. If not , it is in the distributor or coil. If you have spark or the tractor starts, then the problem is in the circuit from the battery to the coil.

A coil discharges a spark when the field is collapsed, that's the job of the points. To test a coil remotely you can apply power to one side and toggle the other side to the ground and it should give a spark to ground. Has to be a complete circuit, electricity always needs to go home.

Jag… welcome to YT! Sometimes guys that talk about these systems all the time don’t realize that even though they are attempting to explain something in a simple way they are actually still going over someone’s head. My apologies if you actually understood what was being said. The field which I think I can call it “magnetic” collapses or goes away when the power to the coil is turned off, that of course makes sense. The primary winding in the coil that is connected to the small terminal that are fed voltage powers up when energized. It is physically next to the secondary winding that connects to the spark output terminal. The powered primary winding excites the electrons flowing through it. When the power is removed from the primary winding by the points opening those excited electrons want to find a place to go. This causes them to jump as a group into the secondary windings to create the spark. That is a very simplistic explanation but adequate for a beginner.
