I was thinking of creating a training aid to show how to trouble shoot electrical problems that typically occur with lawn tractors.

Maybe by attaching all the actual interlocks(working order from spare and trash pic parts), seat, pto, blade/brake, solenoid, starter and battery, etc on the back of the board. Wire them together (in series) with grounds. On the front could be the ignition switch

Any way, the goal would to be to create different frequently known issues by creating shorts, opens and ground problems so that the student could logically work through the problem to locate and repair it.

Any suggestions?
