How To Check For Bad Spark Plug Wires

How To Check For Bad Spark Plug Wires – Spark plugs are small but powerful devices that transmit electrical current from the ignition system to the combustion chamber of engines.

In push-to-start cars, the ignition system still depends on the spark plugs to start the engine when the button is pressed.

Like most car parts, spark plugs wear out over time and need to be replaced. However, this aging is not a sudden event, it takes time and gives signals that these need to be changed:

Ways To Test Spark Plug Wires

A fully functional spark plug should start the engine as soon as you turn the key in the ignition. However, if your spark plugs are failing, you will find that you occasionally need to hold the key in the start position as if to force the engine to start.

If you’re in a situation where it’s difficult to start mechanically, your spark plugs may be worn out and the engine may no longer start, according to Alex Kadoli, mechanic at Bunga. Sometimes the car may not start at all until the spark plugs are replaced.

When your spark plugs are worn out, it is common to find yourself accelerating and the vehicle not responding appropriately. Kadoli explains that when spark plugs wear out, it means they cannot produce enough firepower to effectively mix air with fuel (air-fuel mixture) to accelerate the car while driving. Press the gas pedal.

Peter Amadi, mechanic at Dallas Auto Limited, explains that under normal conditions, when your spark plugs are working normally, the color of the exhaust pipe should be light but not jet black. This is a situation that occurs in all car brands, regardless of whether your vehicle runs on diesel or gasoline.

Symptoms Of Bad Spark Plugs & Replacement Cost

“If black smoke is coming out of your exhaust pipe, one of the things you need to worry about is broken or worn spark plugs. This means that the combustion of fuel in the combustion chamber is not 100 percent or not completely burned. This also means that the air does not mix well with the fuel to burn efficiently. Excess fuel that is not completely burned is emitted as black smoke,” explains Amadi.

When the spark plug works properly, it helps burn fuel efficiently in the combustion cycle. In this case, your vehicle’s fuel economy may be above average. When a spark plug is not working optimally, it is usually because the distance between the spark plug electrodes is either too small or too far apart.

Rather than replacing the spark plug entirely, many mechanics remove it, inspect it, and reset the gap to factory settings. If your vehicle consumes less fuel, this may be due to a worn spark plug.

When an engine misfires, it is usually due to a problem with the ignition system. In modern cars, misfires are often caused by a faulty sensor. Damage to the spark plug wire or the spark plug tip to which the wire is connected can also cause this. Misfires can be detected by intermittent sputtering or stuttering sounds coming from the engine.

Checking The High Tension Circuit

“When an engine misfire occurs, exhaust emissions increase, engine performance decreases and fuel consumption decreases,” says the mechanic. Because of all the possible problems associated with engine misfires, technicians recommend contacting a mechanic as soon as you notice engine misfires. A mechanic can examine the problem and determine the correct course of action to fix it.

Like windshield wiper blades, spark plugs cannot be repaired but replaced. This usually happens after about 5,000 kilometers of driving. However, Amadi points out that there are certain types of spark plugs that have a lifespan of around 20,000 kilometers. If they fail and you have covered that number of miles, there is no way out or shortcut other than replacing them.

“If your mechanic recommends service after 5,000 kilometers, don’t replace critical parts and ignore spark plugs because they haven’t failed yet. “It is better to replace them than to be stuck waiting and stranded on the road, not knowing when, where and when they will stop working,” advises Amadi.

“The thing about car parts like spark plugs is that they can fail at the worst time of the day, when money in your pocket won’t save you. “You may find yourself in a place where there are no spare parts shops and no mechanics to come to your aid,” he adds. Original long-life spark plugs cost around Shs80,000. Performance Tool W80530 Spark Plug Wire Tester

The first sign that you may have a new set of spark plugs is a decrease in fuel economy. Good fuel economy is about the engine running efficiently, and weak spark plugs reduce efficiency.

Misfiring can sometimes occur as the spark plugs become tired. Brief stalls tend to occur more frequently when the engine is under load. This occurs most often during gentle acceleration at highway speeds.

Accelerating in a high gear represents a high engine load situation and is when the spark plug is most likely to skip.

Spark Plug Color Chart (lean, Rich, Fouled, Burnt)

Don’t worry, it’s not just you. They all dropped their first, or possibly their fortieth, F-bomb when their dads made them hold the spark plug while turning the starter on their dirt bikes. Although it seemed cruel and unusual, what followed was his loud laughter and a lifelong revenge plan to get her back; the power of that shock in the back of your mind every time you work on the vehicle’s electrical system.

Fortunately, this is the kind of lesson you only need to learn once, and luckily it’s not the only way to test a spark plug. Like all mechanical things, spark plugs wear out. However, just because the plug doesn’t work doesn’t mean there is a problem. Lack of spark can be caused by many other faulty electrical components.

However, it’s helpful to know how to test the spark plug so you can pinpoint the problem.

A spark plug is a simple device that converts the energy of the ignition system into a spark that ignites the fuel mixture. The short version of how they work is to pass current through the connector so that the arc passes through the gap between the center electrode and the ground electrode.

There’s more, but that’s all we need to know to understand the testing we’re doing because we’re just trying to make sure the connector is up to the task.

Why do we do spark plug testing? Spark plugs are cheap. Therefore, it is not a big deal to replace them in case they break.

There are many reasons for misfires. This could be due to lack of fuel, compression or lack of spark. If there is no spark, it may be due to a faulty spark plug, coil, ignition module, distributor or spark plug wire. So if you get into the habit of throwing parts until your car starts again, you may find yourself in a deeper hole than you thought.

How To Check For Bad Spark Plug Wires

In general, you always want to start with the simplest and easiest solution and work your way to the next solution as you troubleshoot the problem. In case of misfire, the easiest way is to check the spark plugs.

How To Stop Spark Plug Wires From Arcing And Identify Faulty Spark Plugs

Sometimes a visual inspection is enough to determine if a connector is faulty. Over time, the central electrode wears out and no longer functions. But what if that’s not the case? How can you be sure that the spark plug is not burned?

We will talk about two tests you can do to test your spark plugs. Both are relatively simple and require little more than basic hand tools. By performing these tests, you can quickly determine whether the spark plug is the cause of your problems.

Since we are focusing on two different methods for testing connectors, there are different security considerations. One of these requires only a multimeter, while the other requires working with an exposed connector under the hood. For this second method, you should keep these safety tips in mind.

The good news is that you only need a few tools to perform these two tests. There are more professional ways to do this, but since this is a home job we’ll stick with this
