Check the plug on the ignition switch. I have seen quite a few melted causing issues. My 77 plymouth had a problem with overcharging and it was a melted blue wire at the bottom of the column grounding out. Plug on the ignition switch? On the steering column is a flat plug. The Blue wire on my sons 1974 D200 was burnt. I cut them out and put a bullet connector inline.
