It has an electric speedo and has a speed sensor.
speedo connected to gearbox and connected to other end not brken but not working
Look at the left side of the front axle. There should be a cable running there between the lower leg of the fork and the hub of the wheel. That's the speedometer cable. The other end should be connected to the back of the speedometer.
they dont have a cable !! its driven by a speed sensor
Since you replaced the sensor, and the speedometer still isn't working it is possible that you will need to replace the speedometer cable. Check the cable first to be sure that it is still properly connected, and if so replace the cable to see if that solves the problem.
There is no speedometer cable on a 1991 s10. Instead it has a vehicle speed Senor or vss for short. The vss is near the tail end of the transmission and has a green and violet set of wires that connect it to the drac module under your glove box then the draconian module is connected to the ecu which is then connected to the speedometer on the instrument cluster.
It won't be a speedometer cable like the one you're probably thinking of. On the top of the transmission output shaft, there'll be a speed sensor. Connected to this speed sensor will be wires connected by a quick connect coupler. Unplug that, and you can remove the speed sensor with a ratchet and socket. Rather than a cable which goes directly to the speedometer, the F750 will have a speed sensor which sends a signal to the engine ECM, then the ECM sends a signal to the speedometer.
The speedometer is electronic...there is no speedometer cable.
The most common reason for a speedometer to fail is a broken speedometer cable. Loosen the nuts on each end of the speedometer cable. Remove the speedometer cable retaining clips. Reverse the process to install the new speedometer cable.
the speed ometer cable is connected to transmission,unless its a4 wheel drive,then its connected to the transfer case.
Either the Speedometer itself is bad or the speedometer cable is. either one isn't too difficult if you have pulled a dashboard out before.
No cable, speedometer is electric
