Waterproof Motorcycle Automobiales Digital LED Display Volt Meterr

Waterproof Motorcycle Automobile Digital LED Display VoltmeterDescription:The voltmeter range is12-24V, has reverse polarity, short circuit protection, reverse line will not burn.Used to monitor the battery voltage, battery voltage state to grasp, can also be used for other products voltage measurement. Voltmeter to check the battery's state of health, found that low voltage timely maintenance.Specification:Model:CS-257Material: ABSColor: BlackLED indicator light:RedMeasure range:6V-30VWorking voltage:12V-24VDiameter:As the picture show Product Features:Real-time monitoring of voltage, using a battery used under normal operating voltage, extend and protect the battery and engine life. Under normal circumstances there is no motorcycle engines, the voltage 12.5V is above normal. After the launch of motorcycle, generator voltage normal value for 13.5V-14.5V, the voltage is too high or too low is faulty. Wiring guidelines:Back voltmeter indicates "+", "-", the lead connected to the corresponding ACC original car lines, (the key to position ACC position, the voltmeter will work) Package Included:1 X Voltage
