Hope someone can shed some light on a problem. Playing about with my new BMW CAN bus battery charger, when I switch on the charger, it goes through its warming up process and proceeds to charge as it should but all of a sudden the R1200RS sports running light comes on by its self. It may go out by itself but comes back on. When the battery says 100% charged, the little bugger is either on or comes on and the charger wont go into sleep mode (probably because the running light is drawing a small current?) I have tried switching the running light off in the setup menu, having the key in the ignition, out of the ignition. Sure there is a gremlin in my garage . Can someone help?
