Intermittent connections are the hardest to troubleshoot. Always test under load. A simple test light is the easiest and most practical tool to use.
It helps to have an assistant hold the switch to start while testing where you have power and where you don't. Start at the battery posts (the actual posts, not the cable ends). Then systematically start moving the test light to the next connection. Example, across the posts checks good, so move one test lead to the cable end, good, move the other lead to the cable end... And so on until you find where the voltage drop is. Along the way look and feel for hot connections, smoke, discolored insulation, corrosion, etc.
Common failures are the ground cable to the engine or sheet metal, the connections to the amp meter if equipped, the solenoid base ground, fuse connectors.
Just be very careful that the tractor is in neutral and aware it could begin cranking at any time during the test!
