amp meters are not very good for cars as you have to pass ALL the cars current through the guage therefor it has to be hooked up somwhere near the alternator, voltage guages are alot more user friendly as all you need is a power source from any where in the car. just jokes about upper post
"THINK BEFORE YOU POST"
Correct setup for an ammeter involves all the current flowwing through an ammeter.
Ignore the dots, there just to give it spacing
NO AMMETER

the reason for this being a very bad setup, is ammeters effectively have 0ohms resistance. Attatch 0 ohms across your battery, and you um... **** it hard core. A.K.A. short circuiting it.
yeh an ammeter must be placed in series with the other components
but depends wat u wanna measure the amps for,
and u wouldnt need the whole of the car's current if u were wanting to only measure the amp's amp
