If its a 6v system,the speedo bulb should be 12v.

The Special dip switch is the same as a GP so only 4 wires to it. Orange gives it power then the red and blue become live as the rocker is moved. So check you have power on the orange key switch when set to the 3 click position. The speedo bulb becomes live with the rear light which if it isn't blowing as well is strange unless the speedo bulb holder is faulty inside or is the remade type with the screw.
