The Coinmaster CM#4 has 2 battery pack connections, usually one black and one white for a 6 & 8 pack of "AA's". Someone has apparently cut the battery holders off the wires from the detector. I am trying to find out which of these 2 black and red wires connect up to the 8 pack and which connects to the 6 pack. I can see clearly into the detector and the wires are long enough and also connected inside. If someone knows what the 8 pak or 6 pak connects to inside, I can figure out the rest. I just don't want to make a 50/50 guess which wire set is for the 12v and 9v. What board is each wired to?
