Quoted from Quench:
All the driver transistors have their emitter connected to ground. The transistor collectors are individually connected through the wiring harness to the coils. When a transistor gets enough voltage on the base leg, it effectively switches the collector to the emitter (ground) completing the circuit for the coil. You will note 43 volts is connected to all coils. It's the ground line that gets switched to activate the coil.
So I was chasing two problems then, I think I understand.
Q19 has been replaced, and no longer C-E-G short exists.
Q15 does not show a short C-E-G.
As far as I can see, wiring to the right solenoid (left EOS corrected) is correct. I'm unsure on this.
One thing I do know, for sure, is that the EOS switch is shorted - opened or not - on the right coil. Did a sanity check just now.
The short exists across all three lugs on the coil.
I cut one leg of the EOS switch out, and it's registering correctly.
I show continuity across all three lugs on the right coil with the EOS connected - from one leg of the switch, switch wired on lug 1 and 2, checking continuity to all lugs. EOS open or closed.
Delving deeper on the solenoid, banded side far left, calling this lug 1, I show continuity with all wires clipped from 1 - 2 - 3, from 2 - 3, from 1 - 3.
Same test on another coil shows no continuity on 1 - 2, but continity between 2 - 3.
Dang it! I must have a bad solenoid.
