IN, In addition to the good advice below, I additionally use and recommend a 10 ohm current limiting protection safety resistor in that excitation voltage circuit that wires from a switched battery voltage source (such as the Ignition switches IGN output terminal that wires to the ignition coil etc) to the alternators lil No. 1 side excitation terminal ESPECIALLY if you only use a diode and not an idiot charge indicator light. (Depending upon an idiot light bulbs resistance if you used one, you may not even need any other resistor or diode???) If you dont use an idiot light but the 10 ohm resistor I recommend in the excitaiton circuit and should the engine still run on even after the ignition is switched off, then you would need to add the diode (one way current flow check valve). Often the use of the resistor or idiot light may make the diode not even needed. (it will stop any run on problem)

Ive seen them wired direct with no resistors and without any idiot lights that worked just fine while others had to have the diode to prevent run on. Im a strong believer in an ounce of protection is worth more then a pound of cure and as an added safety feature I use the 10 ohm current limiting safety resistor myself, but its your tractor and your choice.

John T PS this is for a GM 10SI 3 wire alternator, dotn forget it requires NEGATIVE GROUND !!!
