So I’m wired up
Blue ground Red ignition hot Black to white MSD I’ve got the green LED at Z1 on the flywheel 1 TDC I re-installed plug leads with #1 aligned with where the rotor points with the green LED on. I can see 12VDC on the 123 dashboard while cranking. Just spent 2 hours double checking verifying etc. no change. I know lots of people are running this with MSD, Ben being one of them. What have I missed? Attached is a pic of my wiring. Yes I know my coil wire is a tad short. Attached thumbnail(s)
