What is an Ammeter. An Ammeter is a measuring device used to measure the electric current in a circuit. It can be used in both series and parallel circuits. This is plausible through the very negligible resistance that the Ammeter introduces to the circuit. It allows us to measure the current running through a circuit element very closely.

Consult your owner's manual on the particular model of meter you own for details on measuring current. When an ammeter is placed in series with a circuit, it ideally drops no voltage as current goes through it. In other words, it acts very much like a piece of wire, with very little resistance from one test probe to the other.
Connect the ammeter leads to the circuit. This process will depend on your model of ammeter. Essentially, the negative ( - ) end of your ammeter will connect to the power source side of the broken circuit. The positive end (+) will connect to the opposite side, so that the ammeter bridges the break.
An ammeter in a main charge circuit measures the electrical flow. It is a device that responds to electrical current by moving a needle. In the most common automotive ammeters, the needle is deflected by the small magnetic forces created when current flows through the meter. These meters are placed directly in the flow path being measured.
