So I've wired up the battery back. 10 9volts and a pair of D cells. The plug that goes into the battery back has a green, black, brown and red wire. I'm pretty sure the black and green wire are the grounds for the 90 and 1.5 volt packs. Can anyone give me any idea which wire is for the positive side 90 volt and which is for the positive side 1.5 volt?
