The way you've got it set up should work.
If the opus is faulty then it may just require replacing. If you are draining the battery and nothing is switched on then you could have a short circuit, this problem could lead to your car not only being drained of battery, but also being surrounded by firemen next time you return.
I;d get a multimeter and see if there is any voltage going through areas that you didn't expect it to be.
