Husqvarna 550 epos not generating loop signal to connect with charge station

Can’t get a 550 to connect to charge station, otherwise operates fine. Charges fine.

I’ve replaced front loop sensor, motherboard and loom , updated firmware and still won’t connect. At the end of the line with what tech support can help with. Any ideas as to what the problem could be?

Check the charging station board.

I assume you generated a new loop signal. Did this finally resolve?

Nope. Tech support useless as always. I’ve changed out every board involved in the loop signal process into other mowers and it works fine. Put them back into the problem mower and it won’t generate a loop signal.
