voltage gauge wiring diagram
About the voltage gauge wiring diagram, first remove the reading lamp assembly and wait beside the tools and materials. This is the original wiring. The DVD was installed on the car as soon as it arrived. I kept an eye on the wiring. Since the interior rearview mirror was still manual at that time, considering the installation of automatic anti glare rearview mirror, I left more positive and negative poles of acc1 and reverse Lamp + poles, and went directly into the ceiling.
It's really convenient when I go to the interior rearview mirror later. Connect the three wires directly and fix it. It's also simple to connect the voltmeter this time. Directly connect the positive and negative of acc1 and wrap the tape to expose the right connector I made originally. Redo a female plug and crimp the power supply of the rearview mirror and the voltmeter together.
After crimping, try to see if it can be displayed. The LED also flashes. The voltmeter also has alarm buzzer and temperature display. You can set cyclic display. The probe is arranged. This is the original thermometer and hygrometer. There is no background light and it is not a digital display. This time, the voltmeter is just on, and a digital display temperature display can be seen at night.
Finally, compared with this voltmeter with fluke's multimeter, it was found that the voltage was 0.2V low, and there was a calibration screw behind it. After calibration, all of them were done well. The wires of the voltmeter were sorted out and did not get into the wire cover. Because the upper part of the wire cover was not caused by Suzuki's original factory, some shook left and right, which was very slight. This time, they just relied on the harness of the voltmeter to withstand it, so they didn't row inside.
Connect the voltmeter in parallel with the consumer [12 V or 24 V]. It is the voltage gauge of the battery. Don't connect firmly before connecting. Try the direction of the voltmeter number with the connecting wire. If you go up high, it's right to fix it. If you don't turn the two wire ends upside down. Be sure to move quickly, or you'll burn your watch.
The voltmeter connected to the cigarette lighter is not very accurate. It is recommended to install a power diode on the positive pole of the battery and then connect the voltmeter in series, so as to avoid unnecessary voltage fluctuation and protect the voltmeter.
