2 humbucker 4 pot pickup wiring help

Abe if you reduce the size of the images to max 1000 pixels on a side, they'll upload easily enough - if you're not sure how to do that, check out Irfanview (freeware) and pretty easy to use. Weirdbits is right though - sounds like you've got a coil splittable humbucker and if so (photos will confirm) - you should be able to use some electrical tape to isolate and insulate the end of the red and white wire (so the bare wire doesn't touch any other metal) and use the diagram as is with the black as the hot and green and bare being grounds.

OK, will try to send. All your input is appreciated

[Abe]

Did the pictures attach to this thread?

[Abe]

May be hard to see; red & white together green and shield together, black separate. Thanks for all you input on this.

[Abe]

OK, so any help out there for wiring these 2 humbuckers to 4 pots for a IB5 bass? Only schematic I can find is for a single wire pickup. Thanks

[Fretworn]

I am guessing, and someone else with better knowledge may contradict me, but the green/shield pair should be ground, red & white are for if you want to split the coils and the black is hot. If you are not adding a coil split switch or a series/parallel switch then make sure the red and white are soldered together and the exposed end covered with either heatshrink tube or electrical tape.

Hi Abe, yes I think Fretworn is on the money, the pickups must have changed to coil splittable pickups.
Grab your multimeter and switch to 20K ohms resistance setting and see what the resistance between black and green/ground and then green/ground and the red/white wires should be the same, I guess around 6-10k ohms.
Now split the red and white wires and try green/ground and red (alone), and green/ground and white (alone) and they should be about half the value you got from the first test.
Do this test for both neck and bridge pickup, the bridge pickups generally have a slightly higher resistance reading but they may be the same.

If this is the case you can do what Fretworn suggested and use the wiring diagram you have if you don't want to add a coil split pot or switch.

If I was building this kit I'd be really interested to hear the difference in the sound between single coil and humbucker, so I'd add a push pull pot to the 2 volume pots.

[Abe]

Great support guys, appreciate that. Few additional questions; do I bend back the 2 volume pot tabs and solder them to the pot? Schematic looks like they are bent back but doesn't show a solder point. Great idea on the push/pull pots. Will let you all know how it turns out and sounds or if I run into any problems. Once again, thanks.

Hi Abe, yes you can bend the 3rd lug of the volume pot but be careful the lug is very thin metal and snaps very easily. I generally solder a short piece of wire on the cheaper supplied pots. You will find with better quality pots the lugs are often longer and a thicker metal and allows you to bend the lug to the pot casing much easier

[Fretworn]

It is also often advisable to sand the back of the pots where you are soldering the earths so that the solder will stick to the pot case.
