Here is my best info.
At the back of the AMP meter there are two terminals. One terminal has #10 wire that goes to the starter area and connects to the big terminal that connects with a Big battery cable to the negative battery terminal. This wire supplies all the systems with power except the starter motor. The other side of the AMP meter has several wires connected, one to the light switch through a fuse, one (heavy) to the Bat terminal on the VR, and one to the Ignition Switch.
All power thus flows through the AMP meter, except the starter heavy current.
The starter button (yours may have a key switch instead with a start terminal) has a wire that goes to the solenoid small S terminal. This wire is what gives the solenoid the signal to close making the starter turn. (by the way, if you jumped between the negative terminal from the battery to this small terminal to make the starter spin, it is not grounding it, it is jumping. Grounding things that are on the negative side of the battery is smoke city.
There should be battery voltage at the ignition coil from the key switch. It should be connected to the - side of the coil, This is the side not connected to the distributor.
Your regulator may be toast. Looking good, is different than having 6 volts every where. See John Ts trouble shooting notes down the page, or from archives. they are finest kind. Disconnect the regulator at the BAT terminal before making any more atttempts to start the tractor. By doing so you will eliminate issues from the running and ignition problems.
NAPA is a reasonable source for components. Good luck, and keep us informed. JimN
