However, there can be physical repercussions for the driver and occupants of the vehicle too. If the vehicle is traveling way above the recommended speed limit, the driver may end up losing control of the car and crashing into another vehicle, object, or person. Serious and even fatal injury can follow. Is your speedometer not working? Now the instrument cluster in your vehicle may not be giving you the wrong reading, but it may be giving you other issues.

Now I know exactly what needs to be done. Matthew 33 years of experience. In response, Otto Schulze invented the first speedometer in These first speedometers were expensive and difficult to find, but by carmakers began to offer speedometers as standard equipment.
DID YOU KNOW: Early speedometers had two gauges: one for the driver, which was located on the dashboard, and a larger, exterior gauge on the front side of the vehicle so the police could read your travelling speed. Broadly speaking, there are two types of speedometers: mechanical and electronic. Mechanical speedometers have been around since and are based on the designs of Otto Schulze. Electronic speedometers are a relatively recent invention and appeared during the 90s.
Mechanical speedometers are often called eddy-current speedometers because they use magnetic eddy currents to display the speed of your car. Mechanical speedometers are analog devices that attach directly to the transmission shaft of the vehicle.
The drive cable is wrapped around the transmission shaft and holds the mandrel inside. As the shaft rotates, the mandrel starts to rotate as well. The other end of the drive cable is attached to a spiral gear. It monitors and controls multiple engine activities, including speed. Another reason for the car speedometer not working is a bad wire. The wires can short out for many reasons, causing the fuse to blow out and stopping the operation of the speedometer.
It mainly happens in older cars. Depending on the type, there is only one repair solution for a bad speedometer — replacing either the speed sensor or the wiring. With proper knowledge about the mechanism of a motor vehicle, you can carry out the repair job at your garage. Otherwise, taking professional help is the most logical thing to do. Click here!!! Using a code scanner to examine the error codes is the first step to reach the root of the trouble.
Connecting the scanner to the ECU will help to pinpoint the failed components. It is necessary to clear the error code to complete the repair process. Find the location of the sensors and check them along with the wires connecting to them for any visible damage. Replace the older one with the new unit in case if you have found any defect.
