The motorcycle tachometer doesn't turn. 1. It may be that the speedometer of the instrument assembly of the vehicle has failed, resulting in the pointer of this meter not rotating. 2. It may be that the wheel speed sensor of the vehicle has a fault, which causes the meter to stop rotating. 3. There may be a fault in the mileage sensor of the vehicle, which causes the meter to stop rotating. Specific needs to be checked.

The tachometer of the motorcycle doesn't rotate because the sensor of the code meter is broken. Remove the speed line fixing nut under the speedometer, draw out the speed line, then support the front wheel and turn it to see if the speed line rotates with it. If it turns, it indicates that it is the problem of the dial. It may be that the reduction gear in the dial is broken or loose, which is more troublesome, because there is no separate speed dial to sell, so it can only be replaced; If it doesn't turn, it means that the speed line may be broken or the counting claw in the front axle is excessively worn. Further check the speed line to see whether it can be pulled out from the front axle. If yes, replace the line. There is no need to replace the speedometer assembly.

Inductive tachometer can also be installed on 6V motorcycle. 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 magneto. As long as the tachometer is appropriate and wired correctly, it will be OK to use it normally after installation. It is difficult and may need to be refitted. The mechanical structure of 6V car is common, and the tachometer is rare. It is not easy to change. It is one thing to say and another to do. When installing the motorcycle electronic tachometer, the green line is connected to the rack, the black line is connected to the positive output of the ignition switch, and the rest is generally connected to the pulse low-voltage line of the large wire package.

125 motorcycle engine tachometer has two types: mechanical and electronic. The mechanical type is to connect the tachometer gear on the engine and the tachometer on the instrument through a flexible shaft meter line; The electronic type connects the tachometer and igniter to the high-voltage package through a speed measuring line (wire). However, due to different models, some connect the speed measuring line to other places, depending on the specific situation.
