boat voltage gauge reading low
The boat's battery voltage standard is 12V. After walking, it will supply power for floating charge, up to 14.2V. The battery protection voltage should not be lower than 10.8V at the lowest. The boat voltage gauge reading low. Use a voltmeter to measure the battery voltage. There are voltage standards written on the battery. 12V or 24V. The voltage may be too low because the generator is broken, or the vehicle body may have too much carrying power, causing damage to the battery.
Low voltage mainly has the following possibilities: virtual connection of power supply, electric door lock, battery connection, power switch, and the possibility that individual battery is broken, which lowers the voltage of the whole group of batteries. It does not rule out that you forget to charge. Instrument failure, inaccurate display. The battery is aging and can't store much electricity. It needs to be replaced as a whole. First charge the battery to see if the power is turned to the end. Check whether the electric lock is falsely connected, which line of the battery is loose, and whether the air switch is burnt.
What is the reason why the boat shows 12v power shortage? It indicates that the low 12v power is caused by the low battery power. After the above phenomenon occurs, you can check it with a voltmeter and battery tester. Nowadays, marine batteries are basically maintenance free batteries, which are generally equipped with a battery indicator pro (also called a charge indicator) to indicate the battery power or charging level. If the battery voltage measured by the voltmeter is lower than 6V, replace the battery. If it is 8-10V, the battery tester will give more accurate measurement results, and the tester will directly give charging or replacement results. Although the measured battery voltage is 12V, the voltage will drop sharply during startup, and the battery cannot store power, so the tester will give the replacement result. Nowadays, car batteries are basically maintenance free batteries, and generally equipped with a battery indicator pro (also called a charge indicator) to indicate the battery power or charging level. When the battery indicator light pro displays green, it indicates that the battery is fully charged and in good condition; When the battery indicator light pro displays black, it indicates that the battery is low and needs to be charged; When the battery indicator pro displays colorless or light yellow, it indicates that the battery is almost exhausted. At this time, the battery is difficult to recover even if charged, and needs to be replaced.
