I was riding my 2002 FLTCUI home yesterday and when I turned into my drive it quit running. I found that I stopped getting spark to the spark plugs. The bike was running fine up until that point. What would cause it to suddenly stop sparking. I tested the fuses that I thought went with the ingnition system and they tested fine. Should I check all fuses or what else should I be looking at. Wrong time to break down as it is just getting nice in Iowa.
