This is wiring in a (mij) bass with humbucking pickups with 3 conductor wiring..not 2...not 4 (from what I can tell and have gathered).
There is a coil tap switch ( I believe it is a coil tap and not a coil splitting set up. Could be wrong, though).
What's not working is that the Volume pot does nothing, but I'm getting full sound at full volume.
The tone pot works as it should. The 3 way toggle works as it should.
The bridge and neck pickups sound very similar (in their respective 3 way toggle positions),
but the middle position is quite a bit different sounding, as it should be. The output of the
pickups are close in reading at a little over 7k. The bridge is about .15k higher in output than the neck.
(I'm stating this last paragraph to say that I think the 3 way is working properly and I'm not somehow getting the same pickup in positions 1 and 3. )
The 2nd and more concerning problem, besides the volume pot doing nothing, is that the 'splitter switch' (dpdt) kills all sound in the down position, while things are normal (and good sounding) in the up position. It's a 2 position switch. (Not 3. Again I'm talking about the smaller switch, not the normal, Gibson-like 3 position pickup selecting switch).
It's supposed to be a coil tap (or possibly split) switch from what I've read,
and is stock/original to this bass. (at least in design. It's possible it could have been replaced at one
time and wired incorrectly, but I doubt it. I'm thinking everything here is stock and original)
So...Does it appear to be wired correctly? Would the volume pot going bad have any bearing on
what the dpdt switch does, or how it behaves? I put my ohmmeter on the volume
pot across every combination of lugs and got nothing more than 7k. The tone pot 'ohmed out' at 400+k.
Any help beyond wild guesses, lol, would be greatly appreciated.
Thanks in advance.
Please excuse my crude and non-technical drawing of the wiring layout. In this drawing,
Ground is marked 'G' and the white wires (in actual photo) are represented with green lines in the drawing and marked 'w'. Green colored =white. I couldn't very well draw white on white paper. Thanks.
