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.
Why does my Harley Davidson have no spark?
No spark. Good fuel. The service dept. told me that the coil hardly goes bad. It might be the crankshaft sensor. I replaced it and it started.
What kind of coil does a Harley Davidson use?
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. Regardless of which cylinder is on the compression stroke.
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.

What causes a Harley ignition coil to fail?
In most cases, damaged cables and wires cause a worn spark and electrode gaps to plug together, which end up in coil failure. Besides, when the output voltage of the coil rises to a high level, it causes short circuits and burns around the insulation.

Do you need to reset the ECM on a Harley Davidson?
Many people also believe that any modification made to the bike requires an ECM reset; however, this should not be the case. After a few cycles of starting and stopping, the ECM should learn your new setup on its own. In just a matter of minutes and virtually from anywhere, you can reset the ECM yourself by following these simple steps.
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.

What makes a good spark plug for a Harley Davidson?
When considering best spark plugs for Harley Davidson motorcycles our experts created a list of features that would make one spark plug a better choice than other spark plugs. Their list included the materials the spark plug is made from, especially the core.
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 causes a spark plug to go bad at idle?
Rough Idle – At idle, spark plug problems might be evident as more vibration, basically a cylinder misfire that occurs only at idle. Poor Performance – On acceleration, spark plug are under particular demand to deliver a strong spark to ignite more fuel and generate more power.
What causes a motorcycle to have no spark?
If it is determined that your motorcycle has no spark; do not just assume that the problem is your coil. There may be an underlying issue. You may have a dead short effecting voltage delivery to your coil. You may have a bad sensor, ECM or TSSM.
What happens when there is no spark from the ignition coil?
1 Power. Two positions of the ignition switch provide power to the positive primary post of the ignition coil. 2 Signal. With no external signal to the coil negative primary post, voltage would travel through the ignition coil windings without inducing any secondary spark. 3 Flow. 4 Open Circuits. …

Why does my spark plug on my Harley not work?
If the plug has oil on it, then it’s oiling up and may not work efficiently, potentially causing a misfire or stuttering under hard acceleration. If it’s just dark or black the bike could be running too rich. A heavy accumulation of carbon on the nose can cause a leakage path to earth.
What kind of spark plug does a Harley Davidson use?
NGK and Autolite among others have always been a preferred performance plug for Harley motorcycles. In addition it is often more convenient to use aftermarket spark plugs aside from the enhanced performance. All sparkplugs listed meet or exceed manufacturer specifications.

What happens if there is no spark in the ignition coil?
Hence, without this high voltage, there is no spark and, consequently, internal combustion cannot take place within the engine. Simply put, the bottom line is without spark the engine doesn’t run.
What should resistance be on a Harley Davidson ignition coil?
Measure the resistance across the two smaller terminals on the coil. The meter should read between 2.5 and 3.1 ohms. Set the ohmmeter to read resistance on the “Rx1000” setting. Measure the resistance across the two larger terminals on the coil. The ohmmeter should read between 10,000 and 12,500 ohms.
How does the coil work on a Harley Davidson?
The coil consists of two winding’s of wire, the primary and the secondary. 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.
