marine voltage gauge not working
The better the marine battery, the purer the electrolyte, and the smaller the self discharge rate.If the marine is stopped for a long time, the battery will self discharge and the voltage will gradually drop. Generally, it is difficult to start the car after it is stopped for about half a month; If the marine is stopped for more than three months, the battery will be completely discharged. If the battery is not disconnected and there are still electrical components working on board, the process will be shorter . At this time , the electrolyte will crystallize on the electrode plate, causing irreversible damage to the battery, and the battery life will be greatly shortened.
Therefore, for a marine that has been stopped for a long time, it is better to disconnect all the connecting wires of the battery and start it every ten days or so. Each time it runs for more than half an hour , let the generator charge the battery to avoid too much drop in battery power , which can effectively extend the service life of the battery .
The marine battery voltage is too low, and the voltmeter contact is not solid. The voltage of the storage battery is too low . The storage battery supplies power for the marine's startup and the electronic equipment in the marine . The marine's storage battery suffers from power loss , so it is a little but the voltage cannot be detected , but it can still ignite . The voltmeter does not display the voltage . It may be that the marine voltage gauge cannot measure the marine's battery voltage because of its false contact . In fact , it is a little bit , so it can make a fire .
When connecting , the marine voltage gauge can be directly connected to both sides of the power supply . It mainly tests the electromotive force of a power supply, while the ammeter cannot be directly connected to both sides of the power supply . If the ammeter is connected to both sides of the power supply , it is very likely that the circuit will be burnt and short circuited , which will also bring certain harm to people . The marine voltage gauge shows 0-12 volts and 0-24 volts. The voltmeter should be used in parallel with the circuit .
