1972 Satelite 360/automatic, Pertronix Ignitor, and a serpentine belt conversion that looks like it came off a newer MOPAR. When the car came in it had the original wiring harness powering the car. Original issue was had to turn the key to run then push a button to start. Customer orders a brand new American Autowire Power Plus 20 harness, brand new ignition switch, and a brand new ignition tumbler. I installed them I still have to push a button to start. I do NOT know how to bench test an ignition switch or an ignition tumbler. Or am I overthinking this dilemna.
