Elec woes, crank, no start after running then parked.

OK, so while running
BATT 13.5V
Coil +ve 8.85V
Coil -ve 3.18V
Ballast, BRN/BLUE (ign 2) 8.97V
Ballast, BLUE w tracer/BLUE (ign 1) 13.39V
Then once stalled, key left in run.
Coil+ve 6.7V
Coil-ve 1.18V so obviously previous post above I messed up and got Coil + and - readings mixed up.
Notice in the video the test light is brighter when on Coil-ve?? Wtf, voltage is lower on that side??
Also no "pulsing" on Coil-ve when trying to start.
That's all I had time for before work.
