Re: Project Questions about Programming and Electrical

I've run into a bit of a problem today. I was testing the whole setup, so I left it running for about half an hour. Every thing seemed fine. I turned it off and went to go run some errands, and when I came home I found that it was on. So I pushed the power switch off and it stayed on. "Hmm...," I thought to my self so I disconnected the battery and it turned off. I reconnected it and left it off. I went to do some chores around my house, came back to my room and found it on again! Somehow, this thing keeps on turning itself on, and I'm not sure how it can do it with the way I have the power switch wired. I'm totally lost on to what is causing this because there is no way for it to happen with the setup I have. You can see that the power relay is connected to the fuse panel, which must receive power from the power switch first in order to even turn on. Here is a rough hand drawn schematic of my electrical circuits:

EDIT: Also it is receiving power from something non-mechanical. So I guess it's leaking through a transistor or something, but I don't see how since they're all connective negatively.
