Welcome to our blog post on breaker points, an important component in various electrical systems. In this article, we will delve into the intricacies of breaker points, their function, common issues, and tips for maintenance. Whether you are a DIY enthusiast, an automotive technician, or simply curious about the inner workings of ignition systems, this guide is for you. So, let's get started!
What are Breaker Points?
Breaker points, also known as ignition points, are mechanical switches that control the timing of the spark in an ignition system. They are a crucial part of traditional ignition systems, commonly found in older vehicles, lawnmowers, motorcycles, and small engines. Breaker points work in conjunction with the ignition coil to generate the high voltage needed to create a spark and ignite the fuel-air mixture in the combustion chamber.
How Do Breaker Points Work?
When the engine is running, the distributor shaft rotates, causing the cam on the shaft to open and close the breaker points. The opening and closing of the points create a circuit interruption, which triggers the ignition coil to produce a high-voltage spark. This spark is then sent to the spark plugs, initiating the combustion process.
Common Issues with Breaker Points
Like any mechanical component, breaker points can experience wear and tear over time. Here are some common issues you may encounter:
1. Wear and Pitting
Due to the constant opening and closing, breaker points can wear down and develop pitting. This can lead to inconsistent spark timing, resulting in poor engine performance, misfires, and even engine stalling.
2. Contamination
Breaker points are exposed to the elements and can accumulate dirt, oil, and other contaminants. This buildup can hinder the smooth operation of the points, causing erratic spark timing and engine issues.
3. Incorrect Gap
The proper gap between the breaker points is crucial for optimal ignition timing. If the gap is too wide or too narrow, it can affect the spark intensity and timing, leading to engine problems.
Maintenance Tips for Breaker Points
To ensure the smooth operation of your breaker points and ignition system, follow these maintenance tips:
1. Regular Inspection
Periodically inspect the condition of the breaker points for wear, pitting, and contamination. Clean or replace them as necessary to maintain optimal performance.
2. Gap Adjustment
Check and adjust the gap between the breaker points according to the manufacturer's specifications. A feeler gauge can help you achieve the correct measurement.
3. Lubrication
Apply a small amount of dielectric grease or ignition point lubricant to the rubbing block of the breaker points. This helps reduce friction and wear, prolonging their lifespan.
4. Timing Adjustment
Ensure the ignition timing is set correctly. If you are not familiar with timing adjustments, it is best to consult a professional or refer to the vehicle's service manual.
Conclusion
Breaker points may be an older technology, but they still play a vital role in many ignition systems. Understanding how they work and properly maintaining them can help ensure reliable engine performance. Regular inspection, gap adjustment, lubrication, and timing adjustments are key to maximizing the lifespan and efficiency of your breaker points. By taking care of this small but crucial component, you can enjoy smooth starts, better fuel efficiency, and overall improved engine performance.
Remember, if you have any doubts or concerns about working on your ignition system, it is always best to seek professional assistance. Stay tuned for more informative articles on automotive maintenance and troubleshooting!
