Aloha! I have a 95 FLHT with an S&S engine and crane igniton components with a Mikuni carb. I need to replace the coil but don't know if it is a single or dual fire. No markings on the coil and the bike was built by someone else. It has three posts for wires plus the plug wire outlets. Any tell tale signs as to whether I have a single or dual fire? Coil is black and stock looking. Any hints would be awesome! I have no clue as to how to tell the difference. Mahalo and stay safe! Greg Mahalo! Everything helps!
