Throwing my hands up on this ignition!

I’ve had issues w MSD boxes too. found by removing the distributor and spinning it by hand, it would spark when spun fast, but not when spun slow.
And spark everytime the white wire was tapped on ground.
I replaced the pickup w a new one and gapped it close.
Spinning dizzy w a drill and measuring AC voltage output, I got about 4.5v
New pickup, it measured 7v
So far, good.
