Is the battery 6v and the system original?
I am going to assume you are using a 6 or 12 volt battery and corresponding coil. Also assuming you are using negative ground. There must be 6 or 12 volts going the the + side of the coil....but -YOU MUST BE ABLE TO TURN THIS OFF!- Make sure your generator or alternator is not wired in a way that can supply power to the coil when the switch is turned off or the tractor will keep running until you run out of gas.

The "-" side of the coil goes to the distributor. When the points close, this completes the circuit and sends a spark to the corresponding wire via the rotor. If you don't have one, buy a $6-7 voltmeter and check your voltage at the coil when the switch is hot. Be careful not to leave the switch turned on for but momentary periods of time if you are not trying to start the tractor. If the points are closed and the switch is left on, you may damage the points and the coil. Good luck.
