HARLEY Unilite Breakerless Ignition System Fits 1984-1999 FXST, 1986-1999 FLST, 1982-1994 FXR,

Mallory unilite breakerless electronic ignition is a dual fire system. Points are replaced with the E-spark module that comes with a photo coupler a signal processor and a power switch. Every time the shutter wheel stops the infrared light from reaching the photo coupler the electronic circuit energizes the ignition coil. When the shutter wheel allows the infrared light to reach the photo coupler the electronic circuit allows the stored energy in the coil to discharge. Order mechanical advance and coil separately. We recommend ordering a 3.0-4.0 ohm coil. For street and highway use.
