Alright - after doing some quick searching on google I came up with a very simple answer for my problem. I don't know if it's related to yours but who knows.
I had very heavy rain today and the sensor in my drivers door may be damp because of it. When the battery cable came loose I Had my windows down (it wasn't raining) and while I was trying to figure it out the rain soaked me and my car...with my windows down. The best thing I can do for now is hope the hot weather tomorrow will dry out my car enough for the moisture in the sensor to evaporate. This is the same as having a short circuit so it's still possible you wiring job may have a fault and some wires are touching.
As for my power outage I believe it was simply a loose battery cable.
Here's the article I found
