How to deal with the failure of automatic charging of motorcycles?
Date: 2021.10.25 Viewed:

Why is the motorcycle unable to charge automatically? What should I do if the motorcycle automatic charging system fails? First of all, we can preliminarily determine that it is a problem with the motorcycle charging system, that is, the charging system cannot meet the power demand of the headlight and the charging demand of the battery at the same time. Next, motorcycle control cable suppliers—Huafeng will give you a detailed introduction to the causes and solutions of this failure.

The first step is to use a digital multimeter to accurately measure the exact value of the charging voltage. Can not only measure the charging voltage above 12V. For AC lighting circuits, the charging voltage of the rectifier to the battery must exceed 13.5V, and it is generally difficult to exceed 14V. For DC lighting circuits, the charging voltage should not exceed 14V. It is less than 16V. If it is lower than this value, there is no guarantee. Fully charge the battery. The multimeter cannot detect the leakage of the battery itself. The usual method is to fully charge it for 3 days, and then install it in the motorcycle. It is recommended to equip it with a suitable custom motorcycle clutch cable, which can fit a fully charged battery. Otherwise, the battery is not enough to drive the starter motor. It is easy to cause battery leakage.

You can use a multimeter to check the discharge of the motorcycle circuit. One is to turn off the ignition switch (key door) and measure the two wires connecting the battery with the K ohm position of the multimeter. Do not connect two wires. The second method is to use the current mode to measure, first turn off the ignition switch, insert the red test lead into the 10ADC range (DC 10A range) of the multimeter, then adjust the multimeter function to the 10A range, and then remove the negative pole. Use the battery and the red test pen to connect the negative wire. Connect the black test lead to the negative pole of the water tank. At this time, the meter reading should be zero (that is, no continuity). A reading indicates that there is discharge in the circuit, and this number is the discharge value.

Then you can start operation. In fact, it is easy for us to increase the working voltage of the charging system to ensure that the headlights are bright enough to prevent battery power loss. Because both the full-wave regulated rectifier and the full-wave regulated rectifier have voltage sampling lines, which are connected to the lead of the DC power lock of the ignition switch. But pay attention to equipped with custom motorcycle cables suitable for motorcycles, and the function of the voltage sampling line is to feed back the voltage signal of the battery to the full-wave regulated rectifier and control the DC output voltage of the full-wave regulated rectifier. After that, if the feedback voltage signal is strong, the full-wave voltage stabilization control reduces the DC output voltage. However, the feedback voltage signal is weak, and the full-wave voltage stabilization control will increase the DC output voltage. Experience has shown that when an open-circuit fault occurs in the voltage sampling line, the voltage signal fed back to the full-wave regulated rectifier will be interrupted. This corresponds to the weakest voltage signal, the full-wave voltage stabilization is out of control, and the DC output voltage increases with the increase of the engine speed. If the DC output voltage is too high, it will damage the motorcycle's electrical equipment. And the battery will be overcharged. The resistance of the open circuit voltage sampling line is infinite, which can increase the DC output voltage. If a resistor is connected in series with the voltage sampling line, the resistor is used to attenuate the voltage sampling signal and the attenuated voltage. The sampling signal input is full-wave stable. After installing the voltage stabilizer, the full-wave stabilized rectifier will correspondingly increase the DC output voltage to match the brightness of the headlights and ensure that the battery is charged.
