3 Ohm Ignition Coil for Harley 1984-2003 31614-83A Replacement | Mactions

Hesitation under load, erratic idling, and hard warm restarts on 1984-2003 Evolution and Twin Cam models often signal a deteriorating ignition coil. Over time, heat cycles break down internal insulation, resulting in weak spark output and intermittent misfires that compromise ride quality.

This 3 Ohm replacement coil addresses these symptoms directly with a fully epoxy-potted housing that seals sensitive internal components against thermal breakdown and road shock. Dual threaded primary terminal studs provide vibration-proof wire attachment, eliminating voltage drops caused by loose spade connections during long touring trips.

Featuring an exact-fit two-hole top mounting flange and forward-facing output towers, this 85mm x 82mm black unit bolts straight onto your FLHT, FXST, FXR, or Sportster frame using original hardware, restoring dependable firing in under an hour.
