Nicked a wire

[Cdntac]

For the sake of experimenting I thought I’d try an A2 in 59.

As careful as I thought I was, I inadvertently nicked the braided lead wire where it’s soldered to the black coil wire.

I’ve soldered them back together but can’t get a reading with my multimeter. I’ve tried other pickups (in case my multimeter was suddenly faulty ) but they’re all correctly showing various K ratings.

To confirm I’m correct:

1) There is a black wire coming from one coil to the baseplate as a ground. It is still soldered and attached.

2) The braided lead wire connects to the other coil’s black wire. This is the solder joint that was broken.

But I’m baffled as to why, when they’ve been resoldered that I’m not getting a reading from the pickup.

I can’t see any other damage.

There is an enamel over the pickup winding wire

Did you scratch this off to create a bare section where it was soldered?

Yep.

I’ve changed magnets before but I’m guessing that since this one was wax potted that I wasn’t as careful as I should have been.

It shouldn’t be this difficult. Solder two wires back together and voila. But nope. lol.

so its braided wire, not 4 conductor, and you have two black wires. one should be ground, one should be hot. the coil wire is pe, but that should connect to the short black wires. if you put a meter on the two black wires, do you get a reading?

Nope. No reading at all.

So I started taking it apart even more and separated the coils.

Somehow, and I don’t know how, the pole piece coil is not providing a reading. The slug side does.

You may have gaffed the coil somehow

so the pole piece coil has a broken connection somewhere...

So after discovering that the pole piece coil isn’t providing a reading via my multimeter, I took apart another pickup I have (made by a small boutique pickup maker) and soldered in the pole piece coil to the slug coil of the SD 59.

And it works.

It’s kinda strange how the pole piece coil got damaged. The wires look fine.

A learning experience. lol.

That’s the weird part. I can’t see how that happened. I took the wrap off the coil and everything looks fine.

But….apparently I damaged it somehow.

the coil wire is about as thick as a strand of hair, so it doesnt take all that much to break it

I could see how the hot wire was broken away from the braided wire at the solder joint since it’s out in the open when getting the magnet out but how that coil got damaged….dunno.

The only wire coming from it is the wire grounded to the baseplate. And it looks fine.

Live and learn I guess.

But with the coil from the other pickup soldered in to the slug coil of the 59 it’s working.

I put it into an R7 — with the A2 magnet I wanted to try in the SD59 — and it sounds good.

So now it’s an SD 29 1/2. lol.

Most likely pulled the wire loose as it comes out from under the winding

The top winding is easy to repair
Just unwrap it a bit and start again

But that bottom starter course, that's a "rewind the whole thing"

If you know someone who can rewind it, that seems like thw best course of action
To reclaim your pickups

Or throw them in a box with some blue tape on it to label it as busted

It’s definitely not the wire running to the coil.

Maybe later today I’ll take it apart even more and look at the ground wire connection to the coil.
