Push button ignition switch help to wire

Yeah, I read again what you had said to test and realized I had tested it wrong. But if I jumper the square pole and and the bug stud it cranks. My sons 71 valiant of course has the same solenoid. And all my wiring matched his, puts out the same test voltage numbers and his car starts and runs all day everyday. I'm really starting to lean towards the possibiliy of it being a bad bulkhead connection or the actual key ignition switch. Either way I'm hopefully narrowing down the culprit. I'm just hoping once I get it to crank over that the rest of it is in working order. Lol.
