I still think you may be using the meter wrong or misinterputing the beeping? Yes, DMM cans beep to show continuity in addition to showing 0 Ohms (or minimal). But a beep when touching + to - is different. With the Nav lights off, do you still have +V on that wire?
If you, indeed, had a +12V shorting to a -12V, you'd have much more obvious issues going on.
As of right now I do not have +12V coming out of the blue wire with Nav lights on or off.
