What are the 3 types of electrical circuits used in automotive?
We will be identifying these items when we look at Automotive Circuits a little later in this book. There are three basic types of circuits: series, parallel, and series-parallel. The type of circuit is determined by how the power source, conductors, loads, and control or protective devices are connected.
What are the different components of automotive electrical system?
Every vehicle has an electrical system that consists of three very important components: the battery, the starter, and the alternator. All these systems work together in a cyclical way, so an electrical problem that starts in any one of these components will affect the other parts of the system.

What is an ISO relay?
ISO (International Standards Organization) relays are very commonly used in today’s vehicles of all types and brands. There are also many different types of non-ISO relays used, but it is fair to say that the majority of relays used today . are ISO types. Relays can commonly have 3, 4 or 5 electrical terminals.
What is a non-solid state relay?
Non-solid state relays have coils, mechanical contacts, springs, levers and other devices. Solid-state relays do not have the mechanical components inside that traditional . relays have. They use circuit boards and electronic components to perform the same switching function in a circuit as a mechanical relay does.
What is a solenoid in a motor?
a plunger inside the coil to move when energized. A solenoid also has an external connection from the plunger that moves another device outside of the solenoid. The most common application of a solenoid is the starter solenoid which causes the starter gear to move and engage with the engines flywheel.
