Males Baca – Ignition coil, is a critical component of the ignition system in both cars and motorcycles. It converts the low voltage from the battery or stator into high voltage needed to generate a spark at the spark plug. If the ignition coil starts to fail or weaken, your vehicle may show specific warning signs. Recognizing these symptoms early can help prevent sudden breakdowns.

Signs of a Failing Ignition Coil You Must Recognize
Below are some common signs that your vehicle’s ignition coil is malfunctioning or completely dead. Spotting them early allows you to take action before it’s too late.
1. Red Spark Plug Flame
A weakening coil typically produces a red-colored spark. Ideally, a healthy spark plug should have a bluish-white flame, indicating strong ignition. If it turns red, the voltage output is no longer optimal.
2. Short Spark Plug Arc
Aside from the color, the spark also becomes shorter. Users often try to reduce the spark plug gap to ensure the spark continues, but this is only a temporary workaround and not a long-term fix.
3. Frequent Spark Plug Failure
A faulty ignition coil can cause your spark plugs to fail more frequently. If you’re replacing spark plugs more often than usual, check the condition of the coil—it could be the root cause.
4. Engine Hesitation at High RPM
When the coil can no longer provide a stable high-voltage supply, the engine may hesitate, especially at high RPMs. You’ll feel this more during acceleration or when climbing hills.
5. Engine Shuts Down When Hot
One telltale sign of a failing ignition coil in cars is the engine suddenly dying after it gets hot, then running normally once it cools down. This happens because internal coil components can’t withstand high temperatures anymore.
6. Excessively Hot Ignition Coil
A physical clue is the coil becoming excessively hot to the touch. If this happens, especially in cars, the coil may no longer function properly and should be replaced immediately.
Emergency Hack for a Dead Ignition Coil in Cars
This quick tip can be helpful if your vehicle breaks down due to a failed coil, especially when you’re far from a workshop.
If your ignition coil feels extremely hot and your car suddenly shuts off, try cooling it down with a damp cloth. The goal is to lower its temperature so it can temporarily function again. This may allow you to drive a little farther to reach the nearest repair shop. However, note that this is only a temporary fix, not a permanent solution.
