I have a jafrum charger and have the plug permanently mounted to the battery. Today I touched the uncovered plug to the red battery terminal while putting it away in the bike. Big spark. Now I have no spark and a very dependable bike will not start. I have run an Accent electronic ignition since 2012 with great result. Now I have no spark. The main fuse is good. Have I cooked my electronic ignition or could it be something else. 1977 CB550f.
