I have a 1955 Buick Roadmaster with a 322 Nailhead. Runs great most of the time. But right now the spark comes and goes at the Points and is weak at times. Any idea what could be causing this?

Points have been changed.

Condensor has been changed.

Coil has been changed.

Still the same problem

Any help would be greatly appreciated!

post-35932-143141748471_thumb.jpgI believe that the circuit that brings power to the points runs through the the ignition switch. Might be a problem with that. I've attached a wiring diagram. As Joe mentioned, there is a resistor in the circuit too, which might be a source to look into. Follow the wires and make sure all the connections are bright and tight as Matt said.
