The ignition system must be fault-free for the speed display to function correctly. Settings must also
be made in the instrument setup. Please follow the instructions in the corresponding chapter.
THE YELLOW CABLE IS CONNECTED TO THE PRIMARY CIRCUIT OF THE IGNITION COIL.
IT MUST NEVER COME INTO CONTACT WITH THE HIGH-VOLTAGE CIRCUIT.
8.3 Installing and connecting the speedometer sensor
8.3.1 Use of the original speedometer sensor
If the vehicle has an electronic speedometer sensor with three connection cables that outputs a
ground signal, this can be used. Hall sensors (two connections) are not compatible with the Chrono-
classic. The signal cable of the sensor is connected to the white connection cable of the instrument.
If no speedometer signal can be detected, the motogadget speedometer sensor included in the
scope of delivery is used.
8.3.2 Using the motogadget speedometer sensor
The speedometer sensor supplied is a reed switch. The magnet supplied is attached to a wheel
using 2-component epoxy adhesive, whereby the distance between the magnet and the wheel axle
can be as desired. The speedometer sensor is attached to the vehicle with a retaining plate so that
the magnet and sensor are parallel to each other. The distance between magnet and sensor must
not exceed 4 mm and the sensor must not touch the magnet. The retaining plate must be stable
enough to ensure that the distance does not change even when the vehicle is in motion. The tigh-
tening torque of the sensor nuts is 1.6 Nm, use screw adhesive (medium strength). One cable of
the sensor is connected to ground, the other to the white cable of the instrument. Please note: the
magnet demagnetizes at temperatures above 100°C (hot brake system).
