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.
Does a Harley coil need to be grounded?
The coils do not need to be grounded to the frame. The only ground the coil should see is the one from the ignition when the circuit is made to discharge the coil to the plug.
