Need a bit of help on a Spitfire 1500. New coil, points, condenser, cap and plugs. Get very weak spark at points - nothing out of the cap. Everything set to specs. Seems to be a short somewhere. My 6 volt truck system kicks out a blue spark - the Triumph shows a weak spark. Battery shows 12+ volts. How do I track a short? Am I overlooking the obvious? Has a Delco distributor, BTW. BW
