voltage gauge for motorcycle
When the fire is surging and moistening, build two electric booms (the array is dirty and the mace is fixed. The regular network should be in line. Add 1ox4. If the red fruit pays for the old makeup. Now it is in force to see the fire between the big team and the regiment. The converted forced coral is now closed. Compared with Jiazheng, the electric control sprouting forced voltage of Zhengzhe is 12 Ⅳ, and the South fire is indeed 131, which is created). Although the cavity no-load voltage is also 12%, but the ignition group will know that the iron voltage is 10V, even V, so it is necessary to consider replacing the battery in time.)
Therefore, to sum up, the voltmeter inserted in the cigarette lighter can not display the key ignition instantaneous voltage value, so it is meaningless. Of course, if you change the line of the cigarette lighter to the normally closed line, you can display the instantaneous ignition voltage.
For normal motorcycle, the battery voltage gauge should be 12.5V, and the working voltage of the generator after starting should be 14V ± 0.7V; If the battery voltage is lower than 12V or the ignition circuit is not used for a long time in the morning, the battery may be switched on for a long time. The instantaneous voltage of ignition by turning the key should generally not be lower than 9V. If the voltage is lower than 9V, either the battery should be replaced or the battery should be charged. It can be known according to the length of time of purchasing the battery (except that it has not been used for a long time). Another case is that the bearing of the starter is worn and the operation is not flexible, resulting in the increase of starting current and the decrease of battery voltage. After startup, if the voltage is lower than 13V, the generator belt may slip, there may be a problem with the generator, or the power load of the whole vehicle is too heavy (try to turn off all consumers). If the voltage is higher than 14.8V or even more than 15V, the generator must be in trouble. It can't automatically adjust the voltage. Turn off the engine quickly! Otherwise, the light person will burn a bulb, and the serious body computer board will also be burned out.
