The meter movement has a current flowing through a coil. That coil is on a magnet. The electromagnet with the needle moves according to the current flow. That flow is established by resistive ladders inside the meter.
PUT A MULTIPLIER RESISTOR IN SERIES WITH THE METER AND SOURCE. RESEARCH 'METER SHUNTS AND MULTIPLIER CIRCUITS', IT TAKES ONLY ONE SMALL RESISTOR.....(OR IF YOU HAVE EXTRA METERS, PUT TWO OF THEM IN SERIES WITH THE LOAD AND SOURCE; THEN ADD THE TWO METER READINGS.)
Has hand instead of digital.
basic principle of analogue clamp meter
Yes
A volt meter will do the job.
You need either a code scanner or a analog volt meter. With the scanner, you just need to read the codes. WIth the volt meter, you'll need a chiltons or hanes manual to see where to hook it up.
If the alternator is only putting out 12 volts then it is defective and needs replacing. It should output from 13.5 to 15.5 volts DC. You will need a digital volt meter to get an accurate reading. Analog volt meter is not accurate enough.

The volt.
in a digital meter you get a digital value of your measurement. but in analog meter you have to check the position of the pin along the scale and find out the value.
Volts
Parallel
It depends on what you want to monitor. Most commonly the volt meter is connected in parallel with the battery or the alternator.
Fixed magnet
Has hand instead of digital.
If by single phase, you mean 120/240 AC; it could blowup in your hand!
