Hi All,
I have just joined the forum as I am helping out a friend to get his radmission bike up and running again. I am in the electronic repairs business for 40 years so I get call upon when people cannot get stuff looked at.
His bike is lifeless with no led display on handlebar mode selector. I have confirmed that one of the connections between the controller and the mode selector (+) is open circuit,with no visable external damage, so a replacement harness is required. The web is full of harnesses available from China which look similar. No site mentions compatible with rad power. Are the pin connections an industry standard or do different manufacturers use their own pin layout. Maybe someone can point me in the direction of a spares supplier for the Rad Power bikes.

The plug on the harness at the controller end is 10 pin
