A friend of mine bought this eagle ultra 2 fish finder at a yard sale and gave it to me. It has no power cable or transducer. The power has two male prongs but they are not marked pos or neg. I would like to see if it would power up before I spent any money on cables. Does anyone know how to determine wich is pos or neg so I do not blow it up?
