LR Baggs M1

[Andrew79]

Earlier this year I bought a D-25M locally. It was installed with an L R Baggs M1 (I think?) pickup.

I have no use for it so I removed it and intend to sell it on Craigslist most likely.

I know nothing about pickups but when inspecting it I noticed it looks like a wire has come loose from it's connection.

Looking at the picture, am I correct in thinking these two points should be soldered back together?

Many thanks for any advice you can provide

Yes, you are correct, the central copper wire which I marked as "1" and 1 belong together.

And it is clear why it failed, that whole thing was mounted/soldered incorrectly as the braided shielding wires should not have soldered on 3 in my picture below. There is no mechanical stress relief the way it was installed!

3 should be the part that goes over the black insulation as mechanical protection of the whole cable. The shielding should have been only fixed by the ground ring number 2. If correctly done there is no soldering required on 2. The ring 2 could just be pressed against the braided shielding. But you can solder if you like.

And the two ears on 3 should be simply bended over the black insulation to hold the cable in place.
Hope that makes sense. So I would completely desolder everything and fix it the right way. Probably 15-20 minutes work.

Also one thing more I noticed. The solder for the signal wire should be at the "eye" and not where I marked with X.
Whoever soldered this together didn't know what he had to do...

Hi Ralf,
Many thanks for your detailed response. I knew LTG would help. I may have more questions for you but thanks again this was really, really helpful.
