What symptoms should you look for in a malfunctioning ATV ignition coil? It is a no for experienced ATV riders.
However, it can be perplexing sometimes to discover it’s not as easy as you believe. So let’s find out more about its symptoms!
ATV Bad Ignition Coil Symptoms
1. Backfiring Black Smoke
ATV symptoms can manifest as engine backfire. For example, when your ATV engine runs lean or rich, it produces a backfire.
So, when there is more fuel than air in the engine, it is rich; when there is more air than fuel, it is lean.
Therefore, whenever this occurs, some unused fuel or what you see as black smoke from the combustion cylinders escapes the exhaust system.
2. Engine Misfiring
Engine misfiring is a common ATV symptom that indicates faulty ATV ignition coils. When you start the engine, it makes a noisy sound, like sputtering or coughing.
When your ATV goes fast, the engine spit and jerks, causing undesirable vibrations.
Finally, the engine may struggle to start or remain idling when you reach the stop sign. Most of these symptoms point to a problem with the ATV ignition coil.
3. Starting Issues
Examine your HT Leads or the high-tension leads. They connect the distributor to the spark plugs.
So, when an ignition coil fails, one or more spark plugs do not receive the proper amount of charge.
For example, it could be due to a faulty ignition coil when you have difficulty starting ATV in cold weather.
However, you can perform a simple assessment on the HT leads to ensure a spark flows from each lead to the spark plug.
4. ATV Stalling
If your ATV ignition coil fails, it will stall while working. It usually happens whenever the weak coil begins to send some unusual ignition sources to the spark plugs.
As a result, your ATV may stop working or struggle to restart after shutting it down.
5. Total Coil Failure
When your spark plugs wear out, the ATV ignition coils are forced to operate at much higher production.
Keeping your spark plugs in good condition can reduce the likelihood of an ignition coil malfunction. In addition, regular inspection will save you significant money over the years.
If the disparity in your spark plug expands due to steady erosion, it requires more voltage to generate a spark in the ATV chamber.
In addition, the increased voltage necessitates more current flow throughout the primary circuit, which can bombard the primary transistor.
Therefore, maintaining all these parts in good working order helps keep your coils in proper working order.
6. Fuel Efficiency
Poor fuel mileage is another specifically linked to damaged coil packs—incomplete combustion results in unburned fuel.
Further, the chemical energy of the fuel is not changed into functional form when the coils mess up to provide constant power for the spark plugs to start generating a spark.
So, when this occurs, the quantity of fuel available for consumption per distance traveled is higher than when the coils are in perfect condition.
7. Extremely Poor Acceleration And Idling
Worn coils, commonly associated with faulty sensors, insufficient fuel supply, and damaged spark plugs, can cause poor acceleration and idling.
So, once the ATV’s coils are damaged, you may realize that the engine is reluctant to accelerate, that there is a notable lag in throttle response, and that the ATV idles rough.
8. Power Reduction
ATVs with faulty ignition coils frequently run rough. It means you may start noticing a rough feel or noise when your ATV is idling. Your ATV’s performance may also suffer.
As a result, a faulty ignition coil can cause weak acceleration or may not start at all.
9. Visible Oil Leakage
The massive voltages and charge converted inside the ignition coil generate heat. Whenever the part is operating normally, the oil usually aids in the removal of thermal energy.
However, if the coil is broken, it can cause overheating, which will sooner or later damage the housing and cause oil to leak from the part.
Conclusion
You should not neglect signs of malfunctioning coils and must address coil problems as soon as possible.
Ignoring the issue will speed up wear on other parts, potentially resulting in costly repair or replacement, regardless of whether you intend to bring your ATV to a mechanic for repair work or consider replacing coils.
my can-am 570 outlander will run fine, for about an hour or two, then just abruptly quit. After it sits for a couple of hours, or less, it will start back up and run fine. Could this be a faulty ignition coil. I have had it in the shop 3 times now, but they cant seem to find anything wrong with it while running.
