Queen, to hopefully add some understanding to the posts you received below, here are my inputs:

A small incandescent "Idiot Light" (basically a resistor that happens to also light up) orrrrrrrrr a 15 Ohm Resistor orrrrrrrrrrrr a diode will work to prevent the voltage thats present on the alternators small (1R) spade connector from backfeeding voltage to the coil which allows the tractor to run even if the IGN switch is off.

The reason for applying that voltage to the alternators small 1R terminal in the first place is to provide it with excitation voltage so the alternator begins to charge prior to it becoming self exciting. The problem is once voltage is present on that terminal when you shut the IGN off that voltage can power up the coil even with IGN off so she keeps running. To prevent that a current limiting voltage dropping resistor or idiot light in the circuit or a diode reduces or stops that voltage from backfeeding the coil yet still allows sufficient voltage and current to initially excite the alternator.

So placing the device in the 1R feed circuit (from coil or ign switch) to the alternator for initial excitation will stop the run on problem.

Got it???

best wishes n God Bless
