In this post i will share with you some useful information about ac vs dc and why it matters to know about it.
Car battery dcv or acv.
Turn the multimeter knob to the next highest option 200 acv.
The meter should be set at the top end of the voltage you are reading.

Alternating current voltage acv.
Alternating current or ac is the type used in houses.

Dc voltage is usually marked as a v followed by a short line with a dotted line beneath it.
Cars use direct current and it s based on a 12 volt system.
The dial may have options from 10 to 1000 on the acv side and 5 to 1000 on the dcv side.
If you just want to check weather or not you have voltage at any given point place it on 10 volts and the needle should max out.
Sometimes it will be denoted with a v instead.

Direct current voltage dcv.
If you are not really into cars then you probably haven t thought about this at all.
It s usually a higher voltage like 120v.
The common circuit flow for all battery operated vehicles are as follows.
Select the dc volts position on your multimeter or the 12v setting if you have a dedicated car battery test range.
Sometimes it will be denoted with a v instead.
To measure direct current a battery for example use dcv or v.
This setting is used to measure direct current dc voltage in things like batteries.
The wavy line after a v is ac alternating current voltage and is for checking the mains voltage in your house.
For example a dc battery can produce alternating current if it is paired up with an ac converter.
Knowing the car battery voltage is important if you want to know how to take care of it better.
This setting is used to measure the voltage from alternating current sources which is pretty much anything that plugs into an outlet as well as the power coming from the outlet itself.
Choose the range setting.
1 convert the 230v ac into 9v which the external charger does 2 send this 9v to the controller pcb 3 from the controller pcb wires will go for battery motor any headlights depends upon the model 6v 4 5ah battery has been connected to the pcb.
Dcv stands for direct current voltage and acv stands for alternating current voltage.
In fact a car battery or any other battery releases dc voltage.
A car battery always produces dc voltage.
Available battery charge.
If you re testing a 12 volt car battery select the next highest option 20 dcv.
