Cars and trucks continue to have increasingly complex electrical systems and diagnosing circuit problems on modern vehicles can be intimidating. But it really doesn't need to be.Power Probe has always been dedicated to providing technicians with electrical testing tools to simplify circuit diagnosing and fault finding.When teaching circuit testing, I try to keep things simple. One of the things I teach is that in most circuits, you will have no more than 5 different parts-1. Source - Where the power comes from (battery, generator, solar, etc.)2. Load - the device being activated (lamp, motor, solenoid, etc.)3. Conductors - used to transfer power from the source to the load and back (wires, cables, chassis, etc.)4. Control - breaks circuit for on/off control (switch, relay, transistor.)5. Protection - protects circuit from overload (fuse, circuit breaker, etc.) |
