Hello, have the following problem. There is no power on the fuel pump (or crash switch). I manually put power on it and the pump then runs perfectly. 12 V is on the fuse 11 (fuel pump). According to the circuit diagram (ADAC), the relay is BEFORE the fuse. This means that the relay should be ok. From the fuse to the crash switch, the 12 V would be lost. If the relay is behind the fuse, however, it could be defective. ue (somewhere behind the amature board) and check, maybe someone can tell me where in the circuit the relay is now sitting (before or after the fuse).
