Does anyone have a wiring diagram for a Vintage V940B? There was no output from it today, so I took the back cover off and checked the battery - it was fine. Then I noticed that the red lead from the battery +ve side was kinked back on itself and the insulation stripped to leave about a 3mm "point" of bare wire. I can't see any obviously broken solder joints, and there's no empty terminals in the multiplug or EQ block. I wiggled the wire about a bit and it's working again, but I'm worried that this red lead should go somewhere. Many thanks in advance!
