I bought a Rider 550 a few weeks back and connected to 2016 Ducati Multistrada 1200 but for the life of me I can't get it to charge. If I use the car charger and mount on the bike it works but when I use the bike mount it won't even when I wire it to the same point. Sent away for a replacement and had one back today and still the same. The male pins on the connector from the bike show 12v on a meter but the pins on the bike mount show 0.01v when on and 0v when off. Has anyone else had this problem? I find it hard to believe they have sent another faulty item but then again, if the other one wasn't faulty why didn't they say that.
