How to prevent a Harley Davidson ignition coil from failing?
By maintaining the spark plugs in good condition, you can prevent the failure of the ignition coil. 2. Keep a check on the tires. It is vital to check whether the tires of your Harley Davidson are in good condition or not. Apart from this, make sure to replace if either of the tires is worn out.
How much does it cost to replace an ignition coil on a Harley?
On average, the total cost of replacing ignition coils would stand somewhere in the range of $150.
How does an ignition coil work?
Firstly, it assists in producing a higher voltage that enlarges the gap between the spark plug. Thus it results in a robust flame kernel at the initial stage of the combustion. In the end, it boosts the torque power of the engine.
What is an ignition coil?
An ignition coil or a spark coil is like an induction coil present in the ignition system of an automobile. Besides, it assists in transforming the voltage of the battery to a large number of volts. Eventually, it kindles a spark inside the spark plugs for igniting the fuel.
What happens if your Harley Davidson spark plugs are worn out?
Keep the spark plugs in good condition. If your Harley Davidson’s spark plugs get worn out, it forces the ignition coils to perform at very high output. Apart from this, when the spark plugs wear down, the gap between every spark plug widens. The ignition coil has to deliver a much higher voltage.
What happens if your ignition coil is bad?
If you notice that your bike is consuming more fuel than usual, it is a cause of concern. Because of the low fuel economy, the vehicle receives less mileage.
How many ohms should an ignition coil be?
Ideally, the reading of the ohmmeter should range from around 10,000 to 12,500 ohms. Lastly, if the ohmmeter’s reading is outside or above the ideal range, then there is a fault in the ignition coil.
