motorcycle battery voltage gauge
First, determine the wiring position according to whether you want to measure the battery voltage or part of the voltage, select the range and model of the voltmeter, and select the appropriate position to fix the voltmeter. The positive pole of the voltmeter is connected to the positive pole of the line, and the negative pole of the voltmeter is connected to the negative pole of the line. The motorcycle power supply is DC. You can install it in the low-voltage DC circuit.
The silver thread is the engine and the heart of a motorcycle. Very important, without it, the motorcycle will have no power! The black one should be a pulse line, which is actually a trigger line. I wonder what model your car is. Ordinary straddle 100 displacement cars are AC ignition. There is only one pulse line output. His circuit is grounded. Pulse lines with displacement above 125 have two outputs. Use the resistance gear of the multimeter to measure its resistance. The displacement of 100 is about 100 ohms. It can also be measured by measuring voltage. When measured with a voltmeter, use electric start or pedal start to rotate the crankshaft, and its voltage output value is between 1 and 2V. The color of its line Honda is blue and white. Black and red are ignition and charging wires. The resistance value is about 500 ohms. The pulse line of DC ignition is better to find. Two output wires and the other three in the same color are the output rectifier of the generator. The failure rate of pulse line is not high and is not easy to break. Once it breaks down, it is a fatal fault and the engine cannot be started.
There may be inaccuracies in the display of the voltmeter gauge of the motorcycle battery. Generally, it's ok as long as the battery doesn't lose power. If the voltage is to be measured, it should be measured with a multimeter. After starting the engine, increase the throttle to about 5000 revolutions, and measure the charging voltage between the positive and negative poles of the battery with a multimeter. During the measurement, the battery in good condition must be installed on the vehicle for measurement, otherwise the measurement result is inaccurate. If the charging voltage can reach more than 14 volts after increasing the throttle, it indicates that the charging state is good. If the charging voltage is insufficient, check whether the rectifier is damaged and does not charge, whether there is a problem with the magneto coil and does not generate electricity, or there is a problem with the circuit of the charging system.
