The on-board voltmeter is used to prevent battery failures and to check the charging of your car. Through the voltmeter you get permanent information about the status of your battery, which is usually not possible in cars because they lack these status indicators.
Connection via two connection wires: red +/ black - .
When the voltage is lower than 11.7V or higher than 19.8V, the voltmeter indicates low or high battery voltage by flashing.
Recommendation: put a 500 mA fuse in front of the voltmeter.
