We have a client in the USA thats experiencing problems with a Quattro 8000 24v. I looked at all the manuals i could not find this sequence of blinking (Video is added). This happens with and without any external power source as a Generator or Shore power. And happens with setting it to On wel as Charger only.
The temperature in the hull is not over 20 degrees Celcius. And there is 25,6V in the service battery's. We already tried to let it rest for a few hours but not did not help. Also checked the connections.
Any tips on what to do.
