Thanks for the information. The car sat for many years and will check wire conditions that could be hidden under insulation or connectors.Would also recommend replacing wire with new. If having strange electrical problems.
Had charging problem caused by wires having internal corrosion. Outer insulation looked ok, but inside the wire was discolored with some green here and there. Also had to use relay for full battery voltage for coil and alternator as all connections and switch were old and discolored in addition to bad wire. 71 Plymouth FYI
