That's why I put mine in an enclosure, with duct or electrical tape covering the bottom of the boards. Minimize the chance for shorting out your board. It could be worse if you damage your auto!

You might have cooked the 7805, but everything else is suspect as well.

This is the caveat when prototyping in this fashion, you have to take precautions. The "stick and mud" approach works well for early work, but it needs to be stable for long term use, so think about that as you build.
