Thanks for your tips
I have no real progress to speak of here, more of a leap backwards
The starter refused to work again, and then the my DD started to act up with vacuum problems and took away the time I wanted to spend on the 200D. Also I got more lazy as the temperature continued to fall
I have a question regarding the starter wiring: How do I jump the starter directly from the battery?
Do I just connect the positive battery pole with the small wire (golden philips screw in the picture below) and off it goes? Or would that short the circuit?
If that doesn't do it, then it is likely that the copper wires I soldered together sperated again...
