    Battery Drain issue is solved. Lesson learned.. Do a full battery load test first. I checked Voltage only and ASSUMED it was good. Installed new battery, problem solved. Thank you everyone for their help.

      I have had a fast drain recently, I can basically watch the voltage drop. Lost 3 volts in about 10 minutes or so.
      I checked with multimeter and saw 0.0 amp draw. Bad meter? It still reads volts fine but could I have fried the meter?
      To lose that voltage it would have to be a crazy high amp draw. Bad battery?

        Forgot to mention that my power antenna stopped working a few days prior to this issue. Could be related?

          Just had my battery checked at autozone, clean bill of health.
