The on-board voltmeter 34593 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 - (the voltmeter has reverse polarity protection).
Recommendation: put a 500 mA fuse in front of the voltmeter.
