No spark when cranking

Since this is a '74.... Gotta ask, has all the seat belt interlock crap been removed? It only existed to kill the ignition ...

This is a bit misleading, because it is not per se in the ignition circuit. It's in the CRANKING circuit. This is easy to fix. Just look under the hood for the manual reset, about the size of a horn relay. There are two yellowish wires, one yellow black. You just wire those permanently together

This device originally breaks the wire to the starter relay
