Put a current meter anywhere with this very handy display. This panel meter requires a DC voltage to run, and then has two thick gauge wires to measure current draw.
Since current sensors are a little more complex than volt meters, and its easy to confuse the wires, please read carefully to understand how to wire it together! The current meter has two sets of wires, one thin (red and black) and one thick (red and black). The thin wire set is for powering the meter itself and must be 4-30VDC. There is reverse-polarity protection on these wires. The thick wire set is for the in-line current sensing. The black sensing wire is tied to the black power wire internally, so depending on how you want to use the meter, you may need a separate power circuit.
The easiest and safest way to use the meter is to have no electrical connection between the powering and sensing current. That is, connect something like a 9V battery to the thin power wires and you can put the current sensor in anywhere you want. As long as the circuits are totally separate this will work great.
