i have this 80's B.C. Rich I bought from a pawn shop, I took it apart to paint it but now i realized the wiring was really complicated and after putting it together its not working how it used to.

there's 3 switches for pickup selection:
-a 3-way for the Humbucker, (full humbucker, off, and coil tapping)
-a 2-way for the middle (off, on)
-a 2-way for the neck (off, on)

then there's one volume pot and one tone pot.

Now the humbucker sounds like a neck pickup with the tone know all the way down, but when I turn on the humbucker and one of the single coils it souds how its supposed to sound. so I don't know what to do.
Any suggestions?

here's a picture of the guitar:

Sorry I can't help, but I just had to tell you that your guitar looks amazing.

Wish I could help...theres definately a wiring problem in there, though. ^^

That's an awesome paint job/control scheme though.

EDIT: Lmao, someone posted the exact same thing a minute ago.

If you post a picture of the wiring on your guitar rather than the (nice) guitar itself it would be much easier to help you out...

Schematics and good photos of wiring connections are best to work from.

To be honest the wiring doesn't sound too complicated

No, it really doesn't sound to fancy.

It could be a bad switch, or a bad pickup. Have you tested the pickups to see if they're working properly?

I'm sorry, I can't make much out of that photo as a lot of connections/components are unclear.

Can you draw the circuit diagram that's on the guitar (i.e. trace each wire and draw it rather than just post the diagram it 'should' look like).

Ok so here's a drawing of the wiring:



The Tone Knob is also working backwards. It muffles when you roll it up and gets sharp when you roll it down.

I'm sorry, but if that's the schematic you were working off of, then that may be why your wiring is off. The squiggly ground wire is just.... ugh.
Anyway, your problem on the pot is probably that you got the wires backwards. switch them.

Not sure which switches you have so test with a multimeter to check. In this diagram:

HB = SPDT ON/OFF/ON
SC = SPDT ON/ON


Shielded cable should only be grounded at one end, make sure the ungrounded end can't come in contact with other metal to create a circuit.

The HB will split depending on which coil is to ground normally, i.e. on this diagram:

North Start = Green
North Finish + South Finish = Blue
South Start = to ground

When the switch goes to 'Blue' the North coil is taken out of circuit electrically so only the South is on.

The 2 SCs are switched off when sent to ground. (Less chance of hum imo).

If it were my guitar I'd use the HB switch to select North/Humbucker/South and a push/pull pot to turn it off so it could also be sent to ground. Choosing North or South Coil would mean you could match it (or not) to both SCs.

Wiring for N/HB/S:

North Start = Green
**HOT OUT from 'Green' terminal
North Finish + South Finish = middle terminal
South Start = Blue
***'Blue' terminal to ground

Send the hot out to the middle terminal of a pp, send the lower connection to vol and ground the 'upper' connection so when it's pulled it goes to ground.

If you want a diagram let me know, it'll be easy to adjust this one.

The guitar is finally finished. The first diagram you gave me worked perfect actually! The guitar sounds just like it was before!

Thanks man!
