Imade some new pictures of my problem. In one picture you can see the red line around the wire.I think threr is the praoblem. If i move wire at there thn the conncetion comes back or losts. One question is how i can open the wire conncetion thing. I tried but it didnt work what i used. Can the xl motor prblem be in the wire? The wire is a bit broken beacause it stugked between gears. Sorry about my bad english.
