Here is an example wiring diagram for a garden tractor that is equipped with a Delco Remy Starter Generator. The below diagram also shows our 5 prong, 3 position ignition switch, and our 4 prong mechanical voltage regulator. Note: You can either operate your accessories such as your headlights off of the "L" terminal of the voltage regulator as shown, or run headlights from the "A" terminal on the ignition switch. Whichever terminal you do not use, block it off with electrical tape or a wire crimp connection. There is no need to polarize a starter/generator after installation.
