How does a single fire coil work on a Harley Davidson?
Single fire coils designate spark to only the cylinder that is on the compression stroke. Spark is delivered to one cylinder at a time. Harley Davidson Ignition Coils are known to fail. The longevity you get from your coil may depend on usage, demand on the coil or environmental conditions.
Where is the spark plug on a Harley Davidson ignition coil?
The primary is the area on the Harley Davidson ignition coil where the wires from the motorcycle’s harness are connected. The secondary of the coil is the area/towers where the spark plug wires plug in. There are two types of coils used on most Harley-Davidsons. Dual fire and single fire. Dual fire coils send spark to both cylinders, all the time.
What’s the difference between dual and single fire coils?
Dual fire coils send spark to both cylinders, all the time. Regardless of which cylinder is on the compression stroke. Single fire coils designate spark to only the cylinder that is on the compression stroke. Spark is delivered to one cylinder at a time. Harley Davidson Ignition Coils are known to fail.
What should the ohms resistance be on a Harley Davidson ignition coil?
The specified ohms resistance for the primary of a 2000 carbureted Softail will not be the same as the primary of a 2005 Ultra. Therefore, it is important to use the correct electrical manual for your ride. When testing your Harley Davidson ignition coil you will be testing ohms resistance.
Single fire coils designate spark to only the cylinder that is on the compression stroke. Spark is delivered to one cylinder at a time. Harley Davidson Ignition Coils are known to fail. The longevity you get from your coil may depend on usage, demand on the coil or environmental conditions.
Why does my ignition coil stop working on my Harley Davidson?
The longevity you get from your coil may depend on usage, demand on the coil or environmental conditions. The coil’s capacity may diminish over time, or simply stop functioning at once. If it is determined that your motorcycle has no spark; do not just assume that the problem is your coil.
Dual fire coils send spark to both cylinders, all the time. Regardless of which cylinder is on the compression stroke. Single fire coils designate spark to only the cylinder that is on the compression stroke. Spark is delivered to one cylinder at a time. Harley Davidson Ignition Coils are known to fail.
Where does the spark go on a dual fire coil?
Dual fire coils send spark to both cylinders, all the time. Regardless of which cylinder is on the compression stroke. Single fire coils designate spark to only the cylinder that is on the compression stroke. Spark is delivered to one cylinder at a time.
What’s the difference between dual fire and single fire on a Harley Davidson?
Dual fire and single fire. Dual fire coils send spark to both cylinders, all the time. Regardless of which cylinder is on the compression stroke. Single fire coils designate spark to only the cylinder that is on the compression stroke. Spark is delivered to one cylinder at a time. Harley Davidson Ignition Coils are known to fail.

Why does my Harley Davidson motorcycle not idle?
After changing the cams to s&s 510s with a gear drive and riding the bike for a week with no issues, it all of a sudden has an intermittent idle problem. I’ll start it, and it won’t idle – it’ll drop to zero and die.
What happens when the Idle is high on a Harley Davidson?
Strange that there are no historical codes since you did say you saw the check engine light come on. (Could be you went through 50 key cycles with no engine issues) When you get off the interstate & the idle is high,,, if you were to power it off and restart the bike, does the idle calm down or does it resume the high idle.
Dual fire and single fire. Dual fire coils send spark to both cylinders, all the time. Regardless of which cylinder is on the compression stroke. Single fire coils designate spark to only the cylinder that is on the compression stroke. Spark is delivered to one cylinder at a time. Harley Davidson Ignition Coils are known to fail.
How to coil a Dynatek dual fire ignition coil kit?
BEST ANSWER: The electronic ignition from the pick-up is two wires one white is 12-volt needs to be on the hot wire to coil. Blue wire were the points wire was, If the bike had electronic ignition you will remove old one. My have to add to wires to make longer. Please make sure the blue wire is not on 12-volts will destroy new ignition.
What kind of sensor plate does Shovelhead 70-84 use?
Electronic ignition Shovelhead 70-84. Single and dual fire. Volt tech sensor plate. Dyna S. Mallory unilite dual fire. Dyna 2000i. Twin Tec internal ignition.
Why is one cylinder on a Harley Davidson not firing?
IMO you are correct, by swapping the primary side wires you effectively “switched coils” and the side not firing is now firing so one would conclude the coil (both) are good. aside from making sure wiring is intact I would next start thinking the ignition pickup was bad.
What is the ignition coil on a Harley Davidson?
The ignition coil on a Harley Davidson motorcycle is an essential component of the ignition system. It consists generally of two sets of wires that are wrapped around an iron core.
How does the spark plug work on a Harley Davidson?
The primary receives 12 volts from the motorcycle and allows voltage to build; transferring voltage to the secondary winding where voltage is increased to thousands of volts and released through the spark plug wires to the spark plug.
