To measure the total emf simply connect the battery and voltmeter with the right terminals , but to measure the terminal potential difference which is less than the emf the voltmeter is connected in parallel with the battery
i think so
Use a multimeter that has both scales on it . All you need to do is change the scale from AC to DC
Voltmeter will give you opposite readings or will not work at all.
There are a number of ways to test an alternator, 1,Set your voltmeter to DC most preferable set the meter to 20volts.2,with the engine running, disconnect one of the battery terminals from the battery head. 2,connect the voltmeter to the battery terminal wires and take your reading.
Check to see if the alternator is working Connect a voltmeter to battery: Without engine running reading should be about 12.8 With engine running reading should be 13.8-14.2 If not bad alternator

Voltmeter connect in parallel with the circuit setting on voltmeter highest range first then to lower range. Ohmmeter we need to use the ohmmeter meter setting connect across the resistor
To connect an ammeter, you must place it in series with the circuit so that the current flows through the ammeter. To connect a voltmeter, you must place it in parallel with the component you are measuring the voltage across. Make sure to set the ammeter and voltmeter to the proper range before connecting them.
Voltmeter or multimeter.
The electrical energy measured by the voltmeter is produced by a power source, such as a battery or generator, that generates a voltage difference. This voltage difference creates an electric potential that drives the flow of electrons through a circuit, causing electrical energy to be transferred and measured by the voltmeter.
Connect a voltmeter across the battery terminals without engine running reading should be around 12.8 With engine running reading should be 13.8-14.2 if you are getting these numbers alternator is charging battery
Connect a voltmeter to the alternator and start the engine. An automotive alternator should read aprox 14.5 Volts when it's running and the battery is fully charged.
