The black wires are not properly soldered to the terminals.
There is no solder on the terminals.
When soldering you have to apply enough heat from the soldering iron so that the solder flows covering both the wire and the terminal. When complete you can still see the outline of the wire under the coating of solder

It is a lightly different type of terminal to the one you have but the principle is the same.

You have to be careful that you don’t apply too much heat and that the insulation on the wire starts to shrink back exposing the wire.
You can try and “tin” the terminal first, leaving the hole exposed, by just soldering the terminal without the wire inserted. Once you have a thin coating of solder on the terminal, pass the wire through the hole, bend it to touch the soldered part of the terminal and then solder the wire to the terminal. You’ll find that it will solder more readily and that you don’t have to hold the iron on for so long.
