The battery was diagnosed as bad. I got the new main battery today, it will be installed by another shop tomorrow. Then I'll take it back to AutoZone for another electrical test.

I stopped by the alt shop today and told them what was going on. If AutoZone shows ripple again, I'll bring the car to the alt shop and they said they will take it off the car and test it again, replace diodes if needed.
