The Electronic Specialties Hands On-Line Electrical Training Cards, No. 186, offer technicians a way to learn electrical troubleshooting through a hands-on training system where users can apply, solder and install all the parts onto the training cards. Each card becomes a working circuit that users build. The 16 training cards cover topics such as basic circuit construction, measuring resistance in parallel, series circuits, relays, diodes, starting system, brakes and turn signals and more. These cards can be used to supplement existing electrical training or as a way to increase troubleshooting proficiency. Dan Sullivan takes users step-by-step through the first 10 cards via Youtube videos. There are more than six hours of video training that applies to automotive, heavy duty, equipment and more.
