Need help badly with charging system

I made a ground from the base of the volt reg to the ground on the back of the alt still nothing changed cleaned the whole bulkhead till it was shiny nothing changed I noticed when I wiggled the key it would charge and stayed even after revving so I thought I found my issue so I had 2 spare switchs I changed to a non ground terminal one no change when rev the charging stops so I switched to a newer style same plug in and I added a ground wire to the terminal and still no change even swapped back to the solid state regulator and then it didn't charge on startup anymore so IDK where I am at with this. I got a alt coming tomorrow ima get it tested before I leave the store
