I'm not much of a mechanic but can do some basics. My original 54 AD was running fine on Sunday. Monday I started it, then it stalled and would not re-start. I think I narrowed the problem down to either the coil or the condenser because it does not seem to be getting spark. Occassionally it will start and run for a few secounds then die. Am I on the right track? and how can I tell if it's the coil or the condenser? should I just replace both?
