Hi,
Would anyone be able to help me with identifying a seymour duncan pickup I have in a 5 string Kinal bass?

It looks just like this:

http://www.seymourduncan.com/product...56770_sj57074/

But its active (hooked up to a 9V battery)

Looking at the SD site, they don't make a 5 string active pickup with exposed pole pieces.

I pulled the neck pickup out and its labelled "67 neck" which makes me think it is/was a SJ5-67 Passive. Its got the normal hot (white) wire and ground wired up to the pot normally. But its also got a red wire hooked up to a battery. The base of the pickup is sealed.

Any ideas what this could be?

Thanks

Link not working. (This one? http://www.seymourduncan.com/products/bass/pickups-for-jaz/5string/sj56770_sj57074/ )

For a straightforward passive single coil pickup, the red wire can only be a coil tap or the other end of the coil. For a stacked coil pickup, it could be the link between the two coils. In either instance, the red wire should not be connected to a battery.

Photographs of the offending pickup, mystery red cable and the rest of your control cavity wiring would help.

Sorry about the dodgey link, but yes thats the one I was referring to.

Agh I knew I should have taken a few photos when I pulled it out! I'm travelling at the moment but I'll get some photos when I'm back.

But yes it looks just like the SJ5 with "67 neck" hand written on the side of the pickup. Bottom is sealed with some black goop. Wires run through a black sheath/insulator and there are 3 wires in total.

But if it is the SJ5, then it should just be 2 conductor? Thus my confusion.

The product description states two-con + shield output cable. There is a limited number of possibilities that such cable can offer. Resistance meter readings will reveal what connects to what else.

Test white to red. Test white to bare ground. Test red to bare ground. Expect two of your readings to be identical. Expect at least one of your readings to be 0 Kilohms.

I would still like to see images of the control cavity. I can imagine active EQ circuitry requiring battery power but not a passive, single coil pickup.
