Charging issue 68 barracuda

Ok car has been completely restored paint engine and all. I parked car for little while and my battery died. I replaced battery and was fine drove car all day no issues. Went to dinner with wife and dead battery. The car is no longer charging. I did same as i did last time. Changed vr and still no charge.
Connect vr wires together no change. Im getting 12 v to push on wire at vr. The alt to stud is 12.3-12.6 when running. I checked power to bulk head getting power in car. What am i missing?
