It has 12 volts regardless of whether the key is even in the ignition or not. Then the lcd wouldn't light up. I brought it back in and reloaded the IDE. Now everything seems to be fine again. If I just knew what half of the screens are for, I'd be doing alright. Time to go back out and hook it up again.
Any ideas what I may have done wrong?

By LCD not lighting up, do you mean the back light wasn't turning on or the text wasn't displayed?
