The ammeter is the factory gauge in your dash cluster that says AMPS on it. It measures current in amperes (or amps for short). The ammeter is hooked up in series with all or most of your current draw so everything electrical goes through it in the stock wiring system. If it opens up (bad wire, loose connection, bad gauge etc.) you're dead in the water.
