Dear all,
I upgraded to PCB 1.3 . It runs quite fine, but I have problems with the charging (again). If I plug-in the charger into the chassis plug (connected to P42), the mower turns into state CHARG and charges the battery. But if the mower hits the stations contacts, I can hear the relay opening, closing, opening, closing, opening... The resistances between my charging contacts (screws) and the charging contacts at the board are 0.02 Ohm.
Had the same issue with the PCB 1.2. Back then I missed two wire bridges ( Old topic of PCB 1.2 ). I fixed that and it worked fine.
But I cannot see any mistakes this time. I took (hopefully) relevant pictures from the board and attach them here.
Fuses:
Back:
Diode under the relay
PCB under INA69
PCB under DC DC Converter
Or is it a software issue? I have to find my USB cable and can come up with a console output as soon as possible.
Edit:
Here is the console output, while the mower gets power via charging contacts:
The station led turns red.
