How do I test a Harley Davidson coil?
How to Test a Harley Davidson Ignition Coil
- Turn off the motorcycle. Allow the engine to become cool to the touch before proceeding.
- Disconnect, by hand, the two spark plug wires from the coil.
- Set the ohmmeter to read resistance on the “Rx1” setting.
- Set the ohmmeter to read resistance on the “Rx1000” setting.
How can you tell if a Harley Davidson ignition coil is bad?
Harleys’ that run on a single-coil engine will make cranking sound, but there will be no spark from the cylinders. If your bike stalls while working, this is another sign that indicates there’s something wrong with the ignition coil. When some irregular sparks are sent to plugs from the coil, the issue occurs.
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.
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 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 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.
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 ohm test does a dual coil Harley Davidson do?
The second (B) being the ION sensor (anti knock thing I think), just leave it out of the test. If you have a dual coil you will have 2 more (C & D) terminals. Test each of these (C & D) to terminal (A) for the primary side ohm test.
What should the spark plug be on a Dyna?
Just disconnect it from the regulator and test the CPK side of the connector. I checked for a Dyna the primary coil side should only be between 0.3 and 0.5 ohms. I remembered 3 ohms from somewhere, maybe it was my truck. Anyhow if your coil is a sealed unit you will have to test the plug going in it.
