What is the function of the secondary coil system in an ignition?

Principle of operation of the secondary ignition circuit The coil is the heart of the ignition system. Essentially, it is nothing more than a transformer which takes 12 volts from the battery and increases it to a point where it will fire the spark plug as much as 40,000 volts.

What do you think is the leading cause of secondary ignition failure Why?

Excessive heat and vibration can cause the insulating material to break down and create internal coil failure. Worn secondary ignition components such as spark plugs or wires can cause a coil work harder, require more voltage, and therefore significantly reduce the operating life of the coil.

Can you ruin an ignition coil?

Ignition coil damage is often caused by underlying issues never addressed in engine misfire repairs. Issues like spark plug gapping, leaking valve covers or moisture intrusion. A proper spark plug gap is crucial to an ignition system and the health of an ignition coil.

What is primary and secondary ignition coil?

Ignition systems have two circuits that result in a spark being fired at the end of a spark plug. The primary circuit is between the battery and the ignition coil. The secondary circuit is between the ignition coil and the spark plug.

What causes damage to ignition?

Ignition coils tend to fail because of bad spark plugs or plug wires. If your vehicle’s fuel-to-oxygen mixture is either rich or lean, therefore, your ignition coils may fail prematurely. Additionally, engine heat and vibrations can cause damage to ignition coils.

What is secondary ignition?

Ignition systems have two circuits that result in a spark being fired at the end of a spark plug. The secondary circuit is between the ignition coil and the spark plug. A secondary ignition circuit consists of three components and is the basis for newer variations of the ignition system.

Should there be oil on my ignition coils?

The coil itself is housed in oil. If the ignition coil isn’t working properly it will overheat. This excess heat can crack the housing and – voila – you’ll have an oil leak. It’s best to have oil leaks fixed right away as they cause tremendous damage.
