Ok so I made this 12v battery meter here: **broken link removed** I've got it on a vero board type thing. I absent mindedly put it on top of a 12v battery and evidently a couple solder joints touched the terminals as a green led flashed a couple times and now it doesn't work. How can I tell what part has screwed up? The last time I fried a circuit the broken part started smoking no such luck this time. I'm guessing the green led might have blown, but from my experience with the circuit it doesn't matter if one led is taken out of the equation, the rest should still go. I have a multimeter and so can measure voltages etc but I've never done anything like this before so have no idea where to start...Thanks for any help you guys can offer
