ground noise in ONE pickup???

[trjazzluva05]

I just purchased a squier classic vibe 60s jazz bass with fender SCN pickups modded in for $300 and it was totally noise free at the store...before I played it at home I took the thumbrest off and switched the bridge with a Badass II bridge. When I plugged it in at home, pickups full on and tone about half away I got ground noise. The weird thing is though that when I soloed the pickups and suprisingly the neck pickup was totally silent all the way up with the tone knob all the way up while the bridge was noisy at the same settings soloed. How can I fix this??? I thought changing the bridge was the problem but I switched it back with the same problem...can I ground the bridge pickup cavity somehow???

If you get noise with one pickup soloed, and not the other, and the noise also appears when the pickups are combined, that tells me that one coil in the bridge pickup may have shorted out or something, so that alone it is a single coil, and paired with the other humbucker adds to 3 coils, which would not humcancel.

When you removed the bridge the first time, did you see a ground wire under it?

It could be a bad/marginal pot for the bridge pickup, especially if someone spent a lot of time getting it hot enough several times with a soldering iron to get a ground wire to bond to it. It could be just a bad solder job somewhere on that pot also.
