Quick m42/cop question/help

Noting that black (I assume ground) coil wire is thick - with an inner/insulated/black wire.

When I wrap things up, is it OK for the inner and outer black wires to be intertwined?

Thanks for any help.

Here’s a picture:



I've reviewed some DIYs on this - can't seem to find any detail on that inner/outer black wire.

my gut tells me it’s OK to intertwine inner and outer black wires and treat them as one when soldering things back together(?)

Noooooooooo. That is the cables shielding.

Can you explain better?

Are coil wires connected in sets of 3 - or sets of 4 ?

3) green + brown + two black wires
or
4) green + brown + inner black wire + outer black wire ?


Edit: I now understand shielding a bit more - it acts as a protectant to inner wire - and should not be in contact with it.

Damn shielded wire. I didn't foresee this.

I've seen installs with neatly trimmed-to-fit wires – but am not coming up with how the shielded wire is best addressed.

So far – I’ve gathered that shielding wire should NOT touch inner wire.

After google searching “splicing shielded wire” – I’m finding DIYs where:
1 - Inner wire is soldered up and covered with heat shrink tubing.

2 – “Wire mesh tape” or foil is applied over heat shrinked inner wire. In some instances – just making sure shielding wire ends connect “does the trick”.

3 – Apply outer jacket of heat shrink tubing over everything.


Again – any input or guidance on this topic would be greatly appreciated. I guess what I really need to know now is what exactly is the shielding’s purpose – and how to best maintain its integrity in a soldered splice.

i have nothing constructive to add except for props on the thoroughness.

Thanks man - I don't like doing stupid shit if I can help it..
