Hi everyone, I'm a guitar tech in Los Angeles. My shop a month back recieved a very nice Ritter bass for repair. It turned out it needed new electronics and I was able to pick them up from Jens Ritter at the NAMM show. Ritter does not make his own electronics so asking him about the wiring is not thorough like it would need to be. Anyways, I wired everything up to the last 3 wires by the pseudo schematic he emailed. I say pseudo because he left out how the toggles are wired, which pickup wires are combined, and where the battery wires go. But he did give me enough to get to this point. I bounced this off of Norik Renson and once I said it has a 9 pin output jack, he laughed and said "do not screw around and guess on this". Here's a pic of the whole things before I wired the toggle and pickups. So here's are the questions and I have pics to explain this better. Number 1. There's a stray blue wire coming from the volume push pull pot on the row as per the pic I posted. Was this a mistake? Maybe it doesn't even belong there? Number 2. There's a white wire that is not very long so it would have to be wired near volume, bass & treble or the parametric EQ. Number 3. Where does the battery connect at the 9 pin jack? Any help will be welcome and praised!!! Thank you!
