Two ways to install a tachometer on a motorcycle. Fitst , Connect the speed line to the tachometer through the engine speed port. Second , through the ignition circuit signal line to the tachometer, one ignition is 1 revolution. The first is mechanical, the second is electronic!

Buy an inductive tachometer. There are three wires on it. According to normal watches, the three wires are black, green and yellow. The black wire is connected to the key transmission line of the key door. The green wire is connected to the ground wire, that is, the grounding wire. The yellow wire is connected to the flameout wire of the igniter . It is usually a black-and-white color. How to connect the flameout wire depends on what igniter you are . You can also connect to the flameout wire of the key door.

Grounding is grounding. Just connect this wire to the frame. The color of the grounding wire is different for different brands of cars. It is usually 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 high-voltage package positions are different in different vehicles.

Just connect the yellow wire in the instructions provided by you to the high-voltage thin wire, which is the signal wire. The trigger line of the igniter and the trigger coil are connected in the same line , which is connected to the igniter by the outgoing line of the magneto . This is more troublesome , but it is more convenient to connect to the incoming line of the high-voltage package . The 6V motorcycle can also be equipped with an inductive tachometer . The wiring of this electronic tachometer is generally connected to the power line of the igniter supplying power to the high-voltage package, and some are connected to the output line of the magneto. As long as the tachometer is appropriate and correctly wired, it is OK to use it normally after installation . Generally , the engine does not provide the electrical signal of speed . Instead , the gear is used to transfer the speedometer to the instrument panel through the flexible shaft. If the engine has no relevant interface, it cannot be added.
