I have found that if you leave the hatch open and let it sit for a while the interior light shuts off. I don't know how long it takes as I have never timed it.

 

I just pulled fuses to the lights/stereo etc. until everything was off, then went about measuring the current draw.

Pulling subsequent fuses can often indicate which is the evil circuit when the current draw drops (it works much better if two people do it, as running back and forth to the meter on the battery gets rather tedious).

 

After several tests, battery was exchanged, seems to have solved the problem

 

On several occasions I've had problem batteries tested at the parts store and been told they were good. They were not. A battery with a bad cell might take a charge and immediately pass a load test, but in a couple days it's down to 10.8v or 5/6 of 13v bc 1 of 6 cells dead. Then one day. Then 1 hour.

Without a full charge, lead acid batteries hate cold weather, and will punish you.

 

After exchanging the battery, the old one was left on my workbench for 3 days. A test at that point showed less than 12 volts and tested very weak. I did test that battery with the same equipment earlier, but after a long charge. It fooled the tester !!! Anyway all is well !!!!

 

Thank you for the follow up, again it was. Faulty Battery.
