Hei conversion Intermittent start?

Ran a multimeter to my coil and hei in the run position. It was giving me roughly 11.50v at each side.

Got a few pics. and a question with a multimeter, what voltage should i read out of the coil wire while cranking? I did that just now and got 9-10volts cranking.

Pics, mind the short pickup wires there. I ran out of connectors and just looped in the wires for testing purposes. It has fired like this so it does get connectivity. And yes, its not firewall mounted here. Hence the red jumper wire on the mount going to the neg. terminal.
