walmart batt charger

[borto1990]

Im I going crazy? I picked up the schumacher battery charger, the 1.5 amp trickle charge job. looking at the jumper cables ect I was thinking I could make another "plug in" to put a power port on if I am ever in a jam. following what the positive lead is off the battery, plugging in the supplied jumper cable leads the positive lead flip flops to the other side. So off the battery, it's the black and white lead, through the plug the black and white lead is now going to the negative jumper cable clamp. is this normal?
