tachometer wiring to coil

How to connect the tachometer of motorcycle? It is a problem that many driving test students will encounter in the process of learning to use cars. Grounding is grounding. Just connect this wire to the frame. The color of the grounding wire is also different for different brands of cars. Generally, it is mostly green or black / white. In fact, it is also the wire connecting the negative pole of the battery. The incoming line of the high-voltage package and the outgoing line of the igniter are the same line, and the position of the high-voltage package is different in different vehicles. The high-voltage package can be found along the high-voltage line of the spark plug cap. It generally has only one wiring. If it is a straddle motorcycle, the high-voltage package is generally installed under the fuel tank. Just connect the yellow wire in the instructions you provided to the high-voltage wrapped thin wire. It is the signal wire.

The trigger line of the igniter and the wiring of the trigger coil are the same line. It is connected to the igniter from the outgoing line of the magneto. This is more troublesome, but it is more convenient to connect the incoming line of the high-voltage package. Wiring method of motorcycle electronic tachometer: the square end is connected to the instrument tachometer core, and the open end is connected to the engine. Tachometer is one of the necessary instruments in machinery industry, which is used to measure the speed, linear speed or frequency of motor. Commonly used in motor, fan, paper, plastic, chemical fiber, washing machine, automobile, aircraft, ship and other manufacturing industries.

The normal tachometer is connected to the output end of the trigger coil [Honda, Haomai, Guangyang, Xingfu, Jialing, Zhujiang, Yihao, Haomai, etc. and most domestic cars as examples]. It is a blue and white two-color line, which can be extracted from the magneto line group or connected from the igniter to work with pulse signal. Remember: a few tachometers are connected to the AC coil to provide speed signal with voltage rise as the parameter. 2. Electric start slips, replace the starting disk {electric start clutch disk}! Or overrunning clutch.

Connect the high voltage primary of the igniter, and the ignition voltage is about 200V. If your tachometer is not designed with high voltage sensitivity, the display is inaccurate. The pulse signal of the tachometer generally comes from three sources, one is the trigger signal, one is the ignition high-voltage primary, and the other is the AC output of the magneto. You can test it separately and use whichever is right.
