There is a fault in the primary wiring of the tractor. This means that there is no voltage getting to the coil when the key is on. The system is getting its voltage from the Alternator. Not correct.

There is a break some where. The #2 terminal should be attached to the Big Bat post on the Alt. The #1 post is connected to the Diode.

This could be part of the problem, If you measure 12+ volts at #1 terminal the regulator in the alternator may be bad. Are you sure it is a 10SI alternator? JimN
