had some electrical issues last sunday. 68 charger. Car was running for about 15 min. Went to shut it off. Starter kept running destroying positive cable at the battery. Replaced starter and still happened. Replaced starter relay. Now my cab and dash lights flicker, tach bounces. Cant be sure that this was not evident prior to issu with starter. This has a new dash harness. Thinking maybe ignition switch. Any and all help appreciated. I cant get to point to replicate. But now my cab lights are flickering and tach bounces. Electrical guy said that he had re pinned wiring on ignition switch plug. I am going to check that and compare to images i have found. I.E. I am not an electrical person.
