How do you check the coils on a 2003 Harley Davidson?
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.
