Cable repair
Cut wire and strip enough wire that you are able to solder together.
I used 3 different sizes of heat shrink tubes that are needed to be put on to wires before starting to solder.

Solder center wire first and put smallest heat shrink tube on to of that to prevent short circuit between + & - wires.
Then solder ground(-) wire
Shrink mid sized heat shrink tube on top of wires and finally biggest heat shrink tube for more support
