An update.
I removed the battery box and found that the leads were not connected to anything because someone melted the contacts away from the plastic housing.
ordered another, have it on hand now.
Seems to me that the battery box should have 3 wires coming off of it. Do I connect the +&- to a ground and attach it to the back of the pot?
also, just to confirm, the ground symbols on the diagram should all be connected to the pots per normal wiring correct?( see arrows on attached pic)
lastly, the diagram shows a feed coming out of wire 3 slot feeding the tone switch, mine is not. Is this something that needs to be addressed or is it the same as the one in the image you posted?
