The purple you put an arrow to goes from the NSS through the bulkhead connected to the starter motor solenoid.
Thanks for the correction, of course, you are correct.

I'll leave it to you the figure out how 12 volts go in one end of the wire and comes out 9.

I'm still not clear on your troubleshooting. You disconnected both ends of the purple/white wire, applied 12V to one end with a jumper wire and the measured 9V at the other unconnected end?




The above voltages were all measured trying to start the engine when it would not crank, correct?
This what we did, we disconnected the purple white wire from the ignition switch. We then ran 12 volts from the battery to the ignition switch end and checked it at the nss. there was 12 volts. I then hooked the wire back to the ignition switch and turned it to start. I only 9 volts again

Under the hood. the outside part of the bulkhead which wire provides power to the to the ignition switch, Does it have a resister that might be going bad.
We are going to take the bulkhead loose to morrow

Check the purple/white wire and the terminals on each end. Something is wrong with that wire if the voltage drops under load.
