What kind of damage would a poorly ground condenser do to the electrical components and/or charging system? I have a recently re-build 1977 Shovelhead (kick start only), new battery, new coil/coil wires, voltage regulator rectifier, new points and condenser, and replaced the Keihin carburetor with a Bendix. It ran for 65 miles before it started cutting out and backfiring through the pipes upon excelleration. When I got it home, the condenser bracket was rattling loose. Now it will not start. I have re-timed it, checked the advanced flyweights, and installed a new condenser. Could my loose condenser have damaged my electrical or charging system?
