1971 dart Only cranks when I jump the relay.
you grounded the yellow? No that should not be correct
Left side "B" s the main battery, the 'big stud.". That is a junction point, and also 1 contact in the relay
Center terminal "S" goes to the starter solenoid, this is the other contact in the relay
Bottom right, S2-18Y is the yellow "start" signal coming to the relay coil from your ignition switch. This is 12V when the key is twisted to "start."
Top right goes to your NSS. This only has one wire, one wire goes to the clutch safety switch with a stick, the brown/ yellow tracer goes to your NSS. THIS ONE IS THE ONE you should ground to test the NSS
So that, plus check that the yellow is delivering 12V in "start." if that happens, and no crank, then it surely is a bad relay
Electrically, you can reverse the wires connect to top right and bottom right. These are each end of the relay coil
