1989 Passion II

I just purchased a 1989 Passion II #256.  The neck pickup was changed at some point and is not working.  The circuit board is rather complex.  Can I get a schematic?

Sorry, I meant Bridge pickup

Looking at where you got it, I think it is a Passion III, but that's just me being anal, sorry Dave, haha. I inspected the circuit board, and the wire from the bridge pickup was barely soldered in place. But the wiring still seems funny.

With the push/pull potentiometer down, the 3way toggle selects the following:

Rear position=Middle pickup only

Middle position=Middle and Neck pickups

Front position=Middle and Neck pickups

 

With the push/pull potentiometer up it selects the following:

Rear position=bridge pickup only (very very quiet both coils)

Middle position=Middle and Neck pickups

Front position=Neck pickup only

So this has me scratching my head. I have no clue what it was originally supposed to do, but it does seem like there is something going on with the bridge pickup. It is extremely quiet. The soldering on the board looks a little sketchy as well. There may be some damage where the bridge pickup was replaced? 

If anyone has any clue of the correct wiring for this circuit board, it would be incredibly appreciated.

Also, the 6way rotary eq knob seems to be working just fine. Just saying.

Thanks for reading this, and thanks even more for a nudge in the right direction, if given!
