yamaha bolt speedometer replacement
1. Disconnect the battery cable to reduce the possibility of accidental electric shock to yourself.
2. Remove the electrical connections from the starter side. There are usually two wires: the positive wire and the negative wire. First remove the positive lead, then remove the negative lead from the starter. You may need to mark the connection with a brush to help you reconnect the connector correctly to its correct terminal. To remove the connection, use an open-end wrench or socket wrench to remove the bolts.
3. After removing the two electrical connections, you need to remove the initiator from the chassis. Before removing these bolts, pay attention to the direction of the starter. You may want to mark the bolt with a paint pencil. Usually only two or three bolts connect the starter to the vehicle.
For some Yamaha series, the idle speed indicator, namely the engine tachometer, does not work. The reason may be that the engine tachometer is damaged or the wiring of the engine tachometer is faulty. The engine tachometer of Yamaha motorcycle is electronically sensed. Unlike some old motorcycle engine tachometers, there is a soft axis that rotates with the engine between the engine and the engine tachometer. Its tachometer is an electronic tachometer that senses the engine speed by checking the ignition signal through a wire connected to the ignition system circuit. Therefore, when the engine tachometer, that is, the idling meter, does not move, you should first check whether there is a problem with the speed measuring line of the engine tachometer, whether there is a fault with the speed measuring line, whether there is a fault with open circuit or short circuit, whether the wiring plug of the line is loose or not, which is more likely to occur with the engine tachometer. If there is no problem with the wiring of the engine tachometer, it may be that the engine tachometer itself is pregnant. The engine tachometer is generally not easy to break, but it is not absolutely not. If the circuit is OK, it is basically a problem with the tachometer. Try a new tachometer. The engine tachometer cannot be replaced separately. Basically, only the instrument assembly can be replaced.
