Check the boss (the thing the cable screws onto) on the back of the speedo.
If it gets loose it will wobble and bind the magnetic coupling. I had this
happen on my tach some years back. Take it apart and carefully stake the boss
back in place.
It might be that it is just dirty. It is magnetically coupled with a circular
magnet spinning inside a steel cup. If there is gunk built up in the cup it
will bind giving the same symptoms.
It could also be a kinked/sticking cable. You can pull the cable out of the
sheath and lube it. I use white lithium grease myself.

Hi Everyone,
My speedometer is working strange. It bounces back and forth between
numbers and it does not read the correct speed. The speed is faster than I
am going.
I have 15 " Panasport wheels with Falken Ziex ZE512 195 x 50 R15.
Advice please.
Thanks,
