The starter circuit relay in the pic above operates in an identical fashion. More Voltage (Pressure) = More Electron Flow (Current), More Electron Flow (Current) = Faster Starter Motor Will Spin and be Brighter The Headlight Bulb Will Be, The battery negative terminal has a huge amount of electrons, you can say billions of billions of electrons, while the battery positive terminal has a fewer amount of electrons. This magnetizes the coil, which in turn causes the armature (pin 30 to 87) to close, completing the load side circuit and the engine cranks. They have a lifetime customer out of me. Since 1974.SM. This is an InfoIn fact, the electrons carry energy with them, which it utilizes in the circuit. Related Post: Oxygen Sensor: 1, 2, 3, 4 Wire O2 Sensor Wiring Diagram. A series circuit is a type of electrical circuit, in which all the components are connected end-to-end one after another in a single line. The close circuit refers to the one where there is good continuity of current flow throughout the circuit. Relays havent changed very much over the years, theyre in old cars and new ones, a good idea never gets old. A vehicle's stereo system sometimes has a separate amplifier, and when installing a new receiver, you generally need to connect the new stereo's speaker wires to the factory amp's output section.
