I have a 2011 Blackline and the other day after I fueled up I noticed The gas light was flashing and Lo Range was displayed. I checked the codes and got a b1210 (fuel sender shorted low/fuel gauge circut open). So I tested the sender resistance and it was in spec. (around 50 ohms at full) I also tested the resistance at the speedo and got about the same reading so I thought the speedo might of died. So I bought a new one (70900475) and installed it and same thing. Now I can't even clear the code. It comes right back. BCM might of died? anything else to check? Bike runs fine otherwise besides blowing out left rear bulbs
