Connect either the yellow or white wire to sense the RPM signal.2. The yellow wire can be wrapped around the spark plug lead.a.Signal strength from the ignition coil is dependent on coil type.b.Coil 2-5 turns around spark plug lead, the more turns the stronger thesignal. A weak signal will not show a reading on the screen whereas a verystrong signal will have a reading which is too high or very jittery. If thereading is incorrect then try putting the 1MΩresistor which is included in thebox inline in the sensor wire.3. If the signal is still unstable, please try to connect the white wire to either theECU rev counter output or to the primary side of the coil or to the pulse wire onan active spark plug cap.SPEED SENSOR Mounting:ACEWELL has several speed sensors; the unit may include one of them. Ifthe model is intended to be connected to a gearbox electronic speed output toobtain the speed reading, no speed sensor will be included.Reed Speed Sensor and Magnet:1. This sensor is universal sensor for motorcycle, find a rotating part to installmagnet (for example disk, sprocket or driveshaft) and a location to install thesensor where it can be aligned to the magnet.2. Align the center of the magnet to either of the sensor marking lines or the sideof the sensor. The magnet must not travel down the body of the sensor.3. Installing the sensor parallel to the vibration direction creates optionalanti-vibration effect.4. Make sure the gap between the magnet and the sensor is within 8mm.SPECIFICATIONSFunctions SpecificationsSymbolMaximum speedAverage speedTemperature 1Max.
