Emax 90s Controller kaputt (mit Einführung)

[Wilhelm5]

Hallo! Ich heiße Wilhelm und ich habe ein emax 90s gekauft. Ich komme aus Schweden aber ein Teil meiner Familie ist Deutscher. Ich spreche es selbst nur passabel, dafür wird meine Frage auf Englisch.

-------------
Recently after driving my emax 90s, I drove it into our garage but when i went to turn it on the next day nothing turned on. No lamps, no horn, nothing. I checked the electrical connections and saw no fuses blown but I eventually found out that i had voltage into the controller underneath the steering wheel but not out. My best guess is that it is broken but no fuse is blown on there either. What is your guys' recommendations for this? We have the possibility to solder the board, perhaps someone has schematics for the board itself?
