Our Fendt caravan has installed an ex factory Mover (built in 2004). Three days ago it worked perfectly. Today I wanted to use it, but it didn’t work anymore…:-( Have already disconnected battery – without success. Battery has 13.5 volts. When I connect the battery, lightly all three LEDs briefly to the black box (control unit …?) Then everything remains normal. Only when I turn on the remote control (without pressing buttons) happens the following: It clicks on or Two relays. After that the red led 7 times looks. After 7 times blinking is a short pause and then the red LED flashes again 7 times. Question: is the 7 times blinking already a error code? What else can it be…? How should I start troubleshooting? Thanks for an answer in advance.
