Shock when Installing Fluorescent Bulb 50VAC between frame and GLASS of Lamp - New Ballast Installed
After scratching my head - I decided to pull the tombstones out and inspect the wiring to make sure there was no sneaky connections and also nothing out of the ordinary. The older ballasts (original diagram are Magnetic Ballasts with PCB) the new ballast are electronic. I contacted the manufacturer and they suggested to verify my grounds for the ballast assembly. Since I had several that were fine and all inline - I verified ground from good unit to ground on unit that I was shocked with. Grounds were good.

So upon pulling the tombstones out and checking the wiring - I tugged on each of the wires, one of the wires just slid out of the connection. While it was inserted in the tombstone connection just fine; it just kind of slid out as if the spring clamp had not locked it in. I removed the wire and installed a new wire into the tombstone making sure it clamped down on the wire. 
After I had done this there was no longer an issue. I assume the wire was close enough to conduct but far enough away to cause the issue. 

I do not understand that engineering wise - but maybe it has something to do with RF, High Voltage and an Air gap.
