5-Circuit Training Aid

Five real automotive circuits on one durable panel — series, parallel stoplamp, horn, cooling fan, and heater. Instructors can place dozens of faults in each circuit and lock the rear doors, or leave them unlocked so students bug the board for each other and test each other. No computer to babysit, no real car to repair afterward.

The five circuits

Series — current flow and resistance
Parallel stoplamp — branched voltage
Horn — switch and load diagnostics
Cooling fan — relay and motor control
Heater — multi-speed motor control

Why instructors keep reordering

The last thing an instructor has time to do is repair the mistakes students make while learning electrical concepts on a real car — or babysit a computerized trainer with a handful of preset faults. This board is deliberately simple: mechanical fault switches, dozens of possible combinations per circuit, and hinged rear doors that lock.

Leave the doors unlocked and the exercise changes completely. Students set faults for each other and diagnose them in turn, which means the class keeps working while the instructor moves between benches. It is the most popular trainer we build, and much of our business is repeat orders from programs that started with one.
