My '06 610 Speedo stopped working. I suspected the pick-up cable but the odometer still works? What is up with that?
It happened to me, too. My instrument has a blue background light; yours should have the amber light, so maybe there are some other differences and maybe what I did won't work with yours. Following a piece of advice read on forums, I disconnected the battery cables and, after some minutes, I connected them back. The speedo has been working properly since then. Someone suggests that you also connect the two cables to each other to create a short circuit, but I didn't try it and I suspect it could damage the bike (but I don't know much about electronics).
Makes sense. The speedo is a mico-processor like a computer. Must need to be re-booted! No, I wont short it!
Don't short it. It's a known "random thing" (without explanation) and widely published about the 610 dashes. Disconnect the negative battery cable from the battery, count to five, reconnect and you're on your way. You *can* disconnect both cables and put them together (without the battery connected at all) momentarily, but it isn't necessary with these systems.
