Ignition Systems Servicing: 3 Best Practices For Those in Auto Careers

A vehicle’s ignition system is a complex, intricate chain of parts working in tandem. Each time an ignition switch is turned, several processes are activated at once. In the end, the car will start up when the fuel-air mixture in the engine’s cylinder is ignited, causing a spark. A car’s ignition system typically performs this action several thousand times per minute for each cylinder in the engine. 

As can be expected, if there’s a break in transmission at any stage during the process, the vehicle will fail to run or run properly. Although the ignition systems of vehicles are built to last, they still require periodic maintenance. When mechanical parts constantly engage, wear and tear on those parts is an inevitable outcome.

Once you become an auto mechanic, clients will expect you to know how the ignition systems in automobiles work and how to fix them when they malfunction. Read on to discover three best practices for servicing ignition systems.

1. Diagnose The Exact Issue

The first step towards fixing any vehicle’s ignition issues is to get an accurate reading of the root problem. However, this is easier said than done, especially for people without proper training from an automotive school.

Just as they vary by make and model, cars also have different ignition systems, and what works for one may not necessarily work for the other. Beyond this, ignition problems may manifest in any number of ways and through a multitude of symptoms. Every ignition issue must be dealt with individually. And understanding the ignition’s components is essential to proceeding correctly.

As mentioned earlier, every car’s ignition system is a chain that involves several parts working together simultaneously. One or more of these components must malfunction for an issue to occur. You’ll need to determine which one it is by examining each component.

2. Follow The Troubleshooting Steps You Learned During Auto Mechanic Training

As soon as you’ve discovered a satisfactory explanation for the ignition system’s malfunctioning, you can start taking steps to fix the problem. 

Some of the most common issues are damaged spark plugs or wires, damage caused by varying resistance in the coil’s winding, and damaged ignition coils caused by excessive engine temperatures.

Damaged spark plugs can cause an automobile’s ignition system to malfunction.

These issues can be fixed by:

  • Cleaning and testing the spark plug
  • Checking the condition of the ignition system’s wiring
  • Adjusting and replacing the contact breaker
  • Checking the coil for dirt and cleaning any residue of dirt on it
  • Lubricating the CAM system and other moving parts of the automatic advance system

3. Adhere to Safety Tips

Auto mechanic training emphasizes the importance of maintaining safety protocols while working. Although servicing automobile ignition systems does not pose a great risk of personal injury, if done according to the book, you’ll still be dealing with a high-voltage system. It’s a smart move to respect those recommendations that have been put in place to ensure your safety.

It’s important to use the right safety gear both during and after auto mechanic training.

Remember to wear safety gloves and glasses, and avoid touching hot surfaces of the car, particularly if the car was recently used. Finally, disconnect the battery when you can to eliminate the risk of electrical accidents.
