Replaced the voltage regulator - same symptoms. I think John Draxler from T-Bird ranch has offered the solution.
I was outside the car and moving the shift lever by hand (reaching underneath the brake booster) and noticed sparks from the transmission linkage. When I got the sparks, the voltage regulator clicked and the lights went out. John's thought was a bad ground from either the battery to chassis or chassis to motor.
I took some jumper cables from battery negative to chassis bolt and another cable from battery ground to engine block. This seems to have fixed it.
I will clean and verify for good ground connections in the daylight tomorrow and let everyone know the results after some "drive tests" tomorrow night.
