humbucker wiring

I've had this kind of fall into my lap - A friend bought an old Schaller p/u (dated 86) to put in his SG and he wants me to do it...but I've only ever done straight pickup swaps, ie 2-3 wire HB for another 2-3 wire HB, or single coils.


This thing's got 5 wires - green/yellow are already soldered together, brown, white, and bare/ground.


Anyhow, does this seem right to you wiring gurus? I've really only learned how to wire stuff as needed, and now I need to know what's going on with 5 wire humbuckers

Its actually only a four-wire... that bare wire is only a shield.

Other than that, your diagram looks good.

It doesn't matter which "end" of the coils are connected in-series... as long as they are actually soldered in-series.

If the pickups are the same, and one has brown-white soldered but the other has green-yellow that means the guy had them out-of-phase... likely installed south/north as well.

okay, I think the pickup may be fucked. it's grounded, properly, and will still hum like a motherfucker. tapping on 3 of the 6 sets of pole pieces w/ a screwdriver gets nothing but the other 3 sets make noise.


i jumped the pickup* directly to the bridge and it's still humming.



* - the underside of the pickup, the height adjustment screws, etc - any piece that made it hum when touching it w/ your hand.

can i test the pickup itself to see if any of the windings connections etc are bad? i'm perfectly open to the idea that i didn't ground it properly but i did it twice and it's still the same.

sounds like only one coil is connected.

take the pup apart as far as you can to determine which colored leads go to which coils, and north/south arrangement.

No problem!

To make it really easy, you can take pics of the wires where they split to the individual coils... then we can walk you through the connections for sure.

as expected, my cell phone camera sucks and can't get detailed pics of the wiring. yellow and brown are going to one coil, green and white go to the other, and the bare wire looks to be grounded to the backing plate

...and it's grounded properly, same resistance on the multimeter as when i touch the contacts together. seems like i probably fucked it up on the install.
