Help Help

Hello dear ones, I hope you can help me because I have an urgent problem. I put a new/used Lima in my Uno II because my carbon fiber brushes were down. It was also very nice for ten minutes. Then my light went out once, as it is in the mood. Already shit in the dark on the highway. Then I was in the workshop, which measured everything and then put on a mother at the Lima, which was probably a little loose. Then it ran off Ch good for a day and a half and this morning, I drive off, drive two minutes and the light went out and stayed out. And that again in the dark on the highway. I am completely helpless just because women and cars, no seriously. I don’t know how to fix this mistake and I need the car so badly. So I pray you can help me. Ideas? Or maybe even the riddle solution?
