I just got a 2005 S50 and the speedometer light won't light I changed bulb but that wasn't it. I measured voltage and it is not present. I have a manual and traced out the wire but on the bike I am having a hard time chasing the wires. The voltage comes from the fuse box then branches out to a couple of spots. The back of the bike it is present but not up at the headlight does anyone know if there is a junction somewhere where the wires are connected?
