I'm swapping out my coil for a neon coil pack and am almost done but I'm not sure about the ballast resistors: someone had told me to add a ballast in line with the coil power wire, i wired everything up, and was getting weak spark. I removed the ballast and tested again and the spark was much stronger, also, I noticed the original ballast that is wired into the bike was getting very hot with the key on not running. Do I need a ballast going to the coil? Is the original ballast temp normal?if anyone can give some guidance I would be very appreciative. Also, I have a dyna s ignition installed.
