Debugging method in instrument: 12V power supply battery is the same, the positive and negative on the tachometer display 0000, oil table LED exhibit of lanterns out one by one, in the tachometer signal line (green line) to touch the positive power supply, display digital change, normal work, the oil gauge signal line (yellow line) is connected to the negative electrode later on, one by one after the observation light bright, that oil surface normal. Automobile, motorcycle, car, digital display electronic tachometer, LED display electronic fuel gauge, combo meter This instrument uses SMD chip electronic components, automatic SMT processing, stable work, installation of small size. Very suitable for retrofit. Working voltage: DC12V. Suitable for two stroke motorcycle, four stroke motorcycle, shell diameter 52MM, maximum engine speed of 9999 rpm. The red line is the positive pole of a power supply (+12V), black line is connected to a power supply anode (-12V). The green line is connected with the rotating speed signal line, yellow line is connected with the oil sensor signal line. Tachometer can be chosen according to different models. Oil scale with adjustable potentiometer, can match the most sensor. Positive power supply please contact in the switch. Tachometer signal lines connected to the ignition of motorcycle please output to the positive line voltage. The method of testing tachometer: 1, connect the positive and negative power, 2, open the switch, tachometer display 0000, and then the signal line to touch the positive power supply, display digital change, normal work. 3, connect the signal line, start the car, you can display speed. Test methods for adjusting the oil scale: 1, connect the positive and negative power, 2, open the switch, oil scale showed a red, then the signal line is connected to the cathode, LED lights slowly all show, normal work. 3, connect the signal line (Note: not the original oil scale used together), fill up, adjust potentiometer slowly makes the LED lamp just lit, such as the oil runs out after a slight adjustment potentiometer LED lights to make only a bright red, OK. |
