Use a multimeter to measure the pins in the motor driver\nto check if the motor is able to operate properly. If the motor is not able to\nrun properly, the motor needs to be replaced.3. Check the tachometer sensorThe\ntachometer sensor is an important part of the engine's tachometer that senses\nthe engine's speed and converts it into an electrical signal that is displayed\non the instrument panel. So if the engine tachometer is malfunctioning, you\nneed to check if the sensor is working properly.4. Check the instrument panel\ncircuitIf all the above checks are OK, then you need to check if the\ninstrumentation circuit is working properly. Use a multimeter to measure the\nvoltage between the circuit on the instrument panel and the instrument panel\npower supply, if the voltage is 0, then you need to check whether the\ninstrument panel circuit is faulty.Package List:1 3.75\" Tachometer Gauge1 \nInstallation Instruction1 Package of fitting\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul
