I agree with Andy Green's comments about the usefulness
of a voltmeter in a car. For modern charging systems
the most one can tell from a voltmeter is a qualitative
'feel' for how the system is doing. If the meter reads
about 13.8 volts then the charging system is regulated
correctly - and charging. Actually, any reading over
12 volts will charge the battery. What is unknown is
the condition of the battery. An ammeter measures the
'quantity' of current flowing thru a circuit and
thereby indicates the degree of charge occuring. For
my money, the ammeter is a MUCH more meaningful guage.
Just my 2 cents worth...
