The speedometer cable, which is connected to the speedometer in the dash and runs through the gearbox, follows a curved route and should have few or no bends or kinks especially in the ends. The cable, powered by the drive shaft, turns a magnet that creates an eddy current. The circular current rotates the speed cup, which tightens the hair spring. As the hairspring tightens, a pointer on the dial turns and indicates the speed. A faulty or broken speedometer cable causes the vehicle’s speedometer to register the wrong speed or stop functioning entirely.
There are many potential causes of a faulty speedometer cable. A thorough check of all speedometer-related components is necessary to determine the problem’s source. When checking the speedometer cable, our expert mechanics will inspect the routing of the cable, detect any damage such as fraying or kinking, and test the connections on both ends. If the cable is frayed or kinked it will need to be replaced and if gearbox oil has seeped into the cable and made its way to the speedometer the speedometer will need to be replaced. Broken drives, faulty speedometer sensors, and deterioration of the cable’s ends are all common reasons for cable malfunctioning. No matter the problem, our expert mechanics will perform a diagnostic check on the vehicle to pinpoint the exact source of speedometer-related troubles.
Ignoring a faulty speedometer cable can cause the speedometer to behave erratically or stop functioning completely over time. Contact our expert mechanics when you first notice problems with the speedometer cable to prevent further problems, such as receiving costly tickets because of inaccurate speedometer readings.
