Default 12v wall wart for car battery jumper

I have a car battery jumper and the wall wart (power plug) was cut (long story) so I have a wall plug that I want to adapt to the jumper- how do I tell which wire coming from the barrel plug (at the jumper) is the positive? I hope this is clear I know it would be easier to buy a new one (part # EEJP200M-2 AC Wall Charger) but times are really tight and I received this as a trade- thanks in advance
