** For Technical School Curriculums! **

You just can't beat live hands-on electrical training when you have a live circuit in front of you that you can test and troubleshoot using your own DMM. Simulating images and graphics on a computer screen to teach electrical principles just doesn't cut it. Been there - done that! Some companies do it that way to save money. It's not the best way for the technician. It will never replace live hands-on electrical training.

You really need hands-on live circuit troubleshooting with one of our electrical trainers and experience live circuit troubleshooting just like you would do it on a "real" vehicle electrical circuit.

All vehicle electrical circuits in autos, trucks, bull dozers, fire trucks and battle tanks (think Abrams) etc, work the same way and they all fail the same number of ways. The most common electrical circuit problems that occur are OPEN CIRCUITS and VOLTAGE DROPS, as well as, shorts-to-ground and shorts-to-voltage.

In other words, electrical circuits all fail in one of 7-8 ways. As you learn to troubleshoot a vehicle electrical circuit using our unique test procedures we teach you in this training program with our circuit board trainers you can troubleshoot any electrical circuit on any vehicle because they all fail the same ways. It's so easy when you know how!

Learn how to troubleshoot auto/truck electrical/electronic circuits with our hands-on troubleshooting training program using live circuits and your own DMM!

These 5 circuit board trainers replicate a wide range of vehicle electrical circuits so students see a wide range of possible electrical problems exactly like you would encounter in a vehicle.
