Problem with a recently purchased used JB

Re: Problem with a recently purchased used JB

Well...

I peeled everything back to where the coil wires hooks up to the initial lead wires. There was continuity on all wires, including the ground. DC on each coil was about 8.35. Together, about 16.7. I even replaced the 4 conductor cabling. Magnet is in the proper position. Reassembled the PU. I'm really surprised it still works, but I'm still getting the same results. Like I said before: It's still very useable...but with a slight quirk to it.

Very interesting in there. I never realized how fine the coiling wire is, or how penetrating the wax can get. There's like thousands of variables you can throw at these components...

Maybe ( and just may be) The magnet has got degausssed.

A good excuse to buy some neo disk magnets...:wink:

That wasn't it either. But I did find a new home for it in my Schecter Omen 6. Basswood body/Maple neck. Compliments this type of guitar nicely, which has a Pearly Gates at the neck. So, for me, it has work out even though there's an alternate wiring setup.

I agree on the degaussed option. Unfortunately, a gauss tester is a little cost prohibitive. It's much cheaper to just drop about $5 on a new A5. If that doesn't do it, it sounds like you've got a broken coil.

I actually used a strong neo disk and waved the north side of the disc to the screw side (south), and watch it actually gain in strength by using a compass and compared the readings to a good working '59 pickup. I'm not sure if this was a clever way to re-gausse a pickup or just mindless wishful thinking...hmmm

And...

I didn't think about it till now, but can the individual coil be checked for continuity by clipping the start lead wire to the finish lead wire with a meter?

Re: Problem with a recently purchased used JB

Yeah, I covered that in post #11, IIRC

I've read that a neo can be used to gauss and degauss, but I've never tired it and can't speak to how reliable it is or isn't. There definitely seems to be an art to the process.

Re: Problem with a recently purchased used JB

The limits on my meter for checking continuity is about 100 ohms. How do I go about checking continuity on a coil with over 8000 ohms?
