I just picked up an 07 wr250f and the speedomoter / odometer isn't working. The background lights up green, but no #'s letters or hello messages - boo. I was told by the previous owner that it stopped working when the battery "bounced around and the ground wire broke" on a ride. The ground wire is attached and bike starts up and all, just no reading on the screen. Sorry, I'm new to the odometers and such, but my guess is the quick connect/disconnect busted something inside the module itself. Anyone take one of these apart? Is there a fuse inside? Has anyone had this issue before? Thanks in advance. I know this is the 400+ forum, but I think the wrs all have the same module..
