Electrical driving me nuts

Thank you very much for the great information. I now remember the 1-2 start/run circuit after reading this information.I am sorry for not listing the year. 1973 Plymouth Duster . Was a slant 6 car when I bought it 26 year's ago. I built a 383/727 and put it in 25 years ago. Thank you again.I am gonna go run this test and re-run all of the wiring again right now.
