No, I was not. It started pouring down rain and I have another car in the garage right now, so I called it a night. I plan on checking it out tomorrow if the weather behaves.

Good to know my hunch was correct about the regulator and testing the alternator.

I think my best course of action is to test the connector wires. If they are ok, then get a new regulator and try it. If it still acts bad, then pull the alternator and get it tested/replaced

What do you think?
