The speedometer in a C900 is a simple magnetic drag device.
"Now at the other end of the wire inside the speedometer cable is a magnet. That magnet sits inside something called a drag cup, which is made of a non-magnetic metal, usually aluminum. The magnet spins as the wire rotates, creating a magnetic field that forces the drag cup to turn in the same direction. Attached to the drag cup is a spindle that connects to the pointer on your speedometer. A spiral spring on the spindle serves to counter the rotation of the drag cup."
In later 9000s and, probably, in NG 900s, the speedometer reads pulses from a pickup on the transmission.
Yellow's problem is most likely a dry or kinked cable.
