Read your screen or indicator if your meter isn t digital.
Rv battery voltage meter.
To determine if the alternator is charging your batteries hook the multimeter leads to the positive and negative cables that supply power to the rv.
This 12 v lead acid meter has a maximum working current of 5ma and can be easily change between two models.
For that reason it becomes suitable for daily operations in a motorcycle cars and golf cart.
A 12 volt battery should read between 12 5 and 12 7 volts when it isn t being used.
Rvs with 50 amp service usually have more refined systems with ac and dc voltage and amperage readouts available.
Rv battery voltage overview.
To add voltage amperage meters on 50 amp service two meters are needed one meter for each leg of the 50 amp service.
Ac and dc digital meters can be purchased online for about 7 to 15.

Check the voltage with the motor off.
The main bragging point of this utipower voltmeter is its accuracy in determining the battery meter and voltage meter of a device.
Resting fully charged 12 volt batteries are around 12 8 12 9 volts and flat dead ones are at 12 0 volts so 12 4 volts on a resting battery means it s about 50 charged.
It should read somewhere around 12 volts.
A 6 volt battery should read between 6 25 and 6 35 volts.
