Automotive ignition system diagram

The Kettering system became the primary ignition system for many years in the automotive industry due to its lower cost, higher reliability and relative simplicity. Photo Credit: Auto Repair LibraryBefore we can fully understand how the ignition system on your car functions, we need to brush up on the basics of internal combustion. The majority of modern electronic ignition systems use full battery voltage at all times.

Modern engines use computer-controlled factory-preset self-adjusting ignition systems that never change their timing, have no moving parts and never need maintenance. Apart from the main charging, starting and ignition circuits, there are other circuits that power lights, electric motors, the sensors and gauges of electrical instruments, heating elements, magnetically operated locks, the radio and so on.

Ignition system operating and timing control on late model cars are accomplished by the engine control computer. Emissions and Ignition systems are an important part to have knowledge of when explaining repairs to your customers. A breath alcohol detector in an automotive ignition system interlock such that an operator cannot start the automobile engine until he has passed a breath alcohol test. How a starting system works: When you turn the ignition key to theSTARTposition,the battery voltage goes through the starter control circuit and activates the starter solenoid, which in turn energizes the starter motor.

Pictorial diagram of automotive starter and ignition systems. I am looking to get help on correctly wiring a keyless ignition setup. Use a new spark plug or spark tester to test for spark coming from the plug wire, if you do not see spark here, test for spark coming from the coil wire to the distributor.

The Motor Vehicle Mechanics ClipArt gallery offers 238 illustrations of motor vehicle mechanics, including circuit diagrams of numerous parts of cars made by several manufacturers. An automotive wiring diagram, whether it is created for a specific system or the overall car itself, is a guide that shows how the wiring works and operates for a specific make and model of vehicle.
