Jun 6, 2017 · In this continuing series about electrical issues in vintage cars, I’d like to cover the five types of circuit failures this week. To summarize what we detailed a few weeks ago, in order for electricity to do useful work, a circuit needs three things: a voltage source, a path for the current to flow, and […]

The first web service for the automated generation of circuit problems. Simple or difficult, numeric or symbolic, you can build fully customized circuit theory exercises, with solution! If you are a student: preparing and passing your electric circuit exams with …

Learning Objective: Identify charging-circuit components, their functions, and maintenance procedures. It recharges the battery after engine cranking or after the use of electrical accessories with the engine turned off. It supplies all the electricity for the vehicle when the engine is running.

Real-time circuit simulation engine is custom-built for speed and interactivity. Easy one-click simulation, from simple resistors and logic gates, to complex transistor-level oscillators and mixed-signal designs.

real circuit, current flows from the positive battery terminal, through the fuse, to the switch, into the load device, through a ground wire connected to the body of the car, through the body of the car, and back to the battery, like this:

When there's an undesired open or break in a circuit, the component the circuit controls will not function. This is often caused by a blown fuse, an open circuit breaker, or a broken wire. The fuse box is a great place to start if an electrical component has no operation.

Review the basic electrical concepts of voltage, amperage, and resistance. Review the components of a basic automotive electrical circuit. Introduce basic wiring diagram symbols. Review the characteristics of voltage, amperage, and resistance in series and parallel circuits, showing how they are used when diagnosing electrical problems.
