Push button ignition switch help to wire

Penstarpurist said

I'l get some pictures and post them for sure. So far the biggest hurdle is it not even turning over, the engine was run in on our break in stand sdo I know it does run. I matched the wiring from the stand into the engine bay, the only difference being obviously the ignition switch is now the one in the car. But I will definitely get several pics and would absolutely be willing to troubleshoot and work with guidance from you guys.

"Things to check:" cranking

IF you are sure it is a 73 (does not have the seat belt interlock) and is this stick? or automatic?

The "start" (crank) path is.........

ignition switch...........through the bulkhead .........to start relay "flag" or "push on" terminal..........through the starter relay coil.........out the remaining "flag" or push on terminal........and to either the clutch safety switch or automatic, neutral safety switch

Either of these switches are GROUND to operate, IE push the clutch in, the switch grounds the wire.

So check with a light/ meter at the "start" terminal of the relay. Should have battery there with key twisted to "crank."

If so, pull the remaining wire off and clip the remaining relay terminal to ground. Now it should crank.

If not, is the relay bad.
