Speedometer Stopped Working Properly
 

My speedometer on my carbide is going all funny and jumping from like 2-40 back to 4 and so on.

I think hey work with magnets on one of the wheels follow the wires to the wheel and see if theres debree interfering.Not sure worth a shot though.

Ya you need to trace back the speedo circuit. On my GTR there is a magnet embedded in the axle and then a pickup that sits right above it. There isn't much clearance in there. If you got any junk (read mud, dirt etc) between them, the pickup may not be able to ready the magnet.

Now my speedometer just decided to quit and doesn't show anything besides the backlight.

Did you ever look where the pickup is to see what kind of shape it is in or if it is even still there?

ya theres a magnet on the axle and the pickup looks fine, can anyone help?

check your wiring between the pickup
& speedometer
they are not very accurate anyway

theres no cuts in the wiring it looks fine and even if the speedometer isn't very accurate it should still be displaying something it does not make sense.
