There is a metal contact that goes under the coil at the coil mounting screw. It is a ground & goes to center were the 3 wire connecter plugs in. Sometimes a guy changes the cap & leaves this in the old cap. It will cause all sorts of problems 1 of which is burning the center electrod. The pickup coil can cause intermitent problems also as it moves & bends the wires when the vacuum advance moves. You have to remove the dist. & take out the shaft to replace it. The condenser is for radio suppression & not likely to cause any problems.
