In this video I will help you think through the basics of your tractor electrical system, particularly the key switch with three positions: off, run, and start. You will understand what happens in each of the three positions, and know how to test your switch to see if it is good or bad. You will learn how to read a wiring diagram / schematic. I invite your comments and questions. Thanks for watching.
