So if you connected a wire as in the diagram below and there was full volume then it indicates a problem with the volume control.
It may be tarnish on the wiper in the control, try winding the control knob back and forth to see if it clears.
Removing the control and dismantling it by bending the 4 tabs out and cleaning the metal wiper surfaces carefully may fix it.
Dont touch the carbon track in the volume control, though a little grease on the carbon track and metal wiper surfaces can help.
