End Cut

How can I tell which wires on my 12V DC adapter are positive and negative if I've cut off the plug end?

I have a 12V DC adapter, and I needed to use it in an electronics project. I cut the round plug end off of it so I could use a breadboard for my project before I go and get a PCB fabricated. How can I determine which wire is positive and which is negative. I don't wanna blow up any Capacitors!

Got a meter?
Test lamp and rectifier?
