How does mechanical motorcycle speedometer work?
The speedometer uses a rotating flexible cable usually driven by gearing linked to the output of the vehicle’s transmission. The effect is that the magnet exerts a torque on the cup, “dragging” it, and thus the speedometer pointer, in the direction of its rotation with no mechanical connection between them.
What does a speedometer cable connect to on a motorcycle?
Typical motorcycle speedometers are not complex pieces of equipment. They consist of a speedometer gauge and a speedometer cable that connects between the gauge and a fitting on the front wheel hub.
How does a cable speedometer work?
How does it all work? As the speedometer cable rotates, it turns the magnet at the same speed. The faster the car goes, the faster the cable turns, the quicker the magnet spins, the bigger the eddy currents it generates, the greater the force on the speed cup, and the more it’s able to pull the pointer up the dial.
How do you calibrate a motorcycle speedometer?
To calibrate your electronic speedometer: 1) With the power off, push and hold the trip button. While holding the button, start the vehicle and continue to hold the button until the display shows “PrE”. You may now release the button.
How do you calibrate a cable driven speedometer?
Press and hold the calibration button located on the speedometer, start the vehicle, and then release the button. Press that button again and then take the test drive. Once you have driven the distance needed, press the button once more and the speedometer will calibrate itself to accommodate the new tire size.
What would cause a speedometer to stop working?
The most common causes of a speedometer that stopped working include are a faulty speed sensor, a broken gear on the speedometer, damaged wiring, or a faulty engine control unit.
Where does a speedometer cable connect to?
back
The speedometer cable is connected to the back of the speedometer and runs through the gearbox of today’s modern cars, trucks and SUV’s. The cable is powered by the drive shaft and turns a magnet that creates an electrical current and sends this information to the onboard computer.
