The construction of ammeter can be done in two ways like series and shunt. The following circuit represents the basic circuit diagram and the connection of the ammeter circuit in series and parallel are shown below. Analog meters have very fine internal wires that flex to enable the needle to move. A company called wema seems to supply what looks like a rebadged version.

The primary purpose of an ammeter is to indicate the charging rate of the generating system and to check on the current of the boats lights accessory and ignition equipment. The ammeter shunt is the device which provides the low resistance path to the flow of currentit connects in parallel with the ammeterin some of the ammeter the shunt is inbuilt inside the instrument while in others it is externally connected to the circuit. They are basically the same. If ammeter shows a positive charge when starter is engaged reverse. Connect ammeter lamp 60 0 60 i only to existing instrument panel lighting circuit. The above 52mm digital ammeter complete with 150 amp shunt seems a very good buy on amazon but i have bee unable to locate a definitive wiring diagram.
Also when measuring current that exceeds 10a which can be handled with the internal one. A dc ammeter and shunt works in a similar waya small amount of current that flows through the main wire is diverted to and measured by the meter. There is a connector with thick wires and connector with thin wires. But coloring of wires vary.
