The jumper was from A-1 to S-5 the key was off.
That's interesting. Key off no power should have gone to the ballast resistor no matter what. Even with the A1 and R6 connections reversed the bulkhead, no power should be getting to the ballast. That's another puzzle or piece of the puzzle.

Lets go back to faiulure to crank.
If there are alligator clips on the voltmeter's leads, clip one to ground and the other to the start signal wire on the relay. Then when you turn the key to Start postion, it should show battery voltage; around 12.5 if it doesn't crank, something lower (like 11 Volts) if it does crank.

IF there is power at the start terminal. Then check if the neutral safety is grounding.
You can jumper the neutral safety (make sure its in N or P) and see if it starts.

If not, its the relay.
If it does crank, then its related to the safety switch.
