Terminal on the starter solenoid to the right terminal on the ammeter see wiring diagram. The main power goes from the battery to one side of the shunt via a 12 gauge red wire and then from the other side of the shunt to the horn relay via a 12 gauge black wire.

Ammeter shunt wiring diagram. A company called wema seems to supply what looks like a rebadged version. Here is the original ss wiring diagram. Most boats make provisions in their wiring for adding in. If there is none this guide is not for you. The construction of ammeter can be done in two ways like series and shunt. 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.
If ammeter shows a positive charge when starter is engaged reverse. There is a connector with thick wires and connector with thin wires. 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. But coloring of wires vary. The following circuit represents the basic circuit diagram and the connection of the ammeter circuit in series and parallel are shown below. You need a wiring diagram with an external shunt instead.
Connect ammeter lamp 60 0 60 i only to existing instrument panel lighting circuit. Also when measuring current that exceeds 10a which can be handled with the internal one. Analog meters have very fine internal wires that flex to enable the needle to move. 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. Reconnect the battery ground cable. They are basically the same.
Everything on the car except for the starter is supplied power via the lug on the horn relay. Refer to the boat and engine manuals for details of the wiring system and ammeter installation wiring diagrams. 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.
