# How do you measure current in this circuit?

I'm building the circuit pictured below..

Impossible to answer, as I can see a bunch of components but do not know exactly what they are. And the connections, eg, the PC board wires, is unknown also.

Where do you want to measure current? the circuit has about 30 component pins with probably 50-100 interconnections, each of which has a current.

How can you even attempt to build it without the information missing, as noted above.

To repeat, current measurement is done by connecting an ammeter in series, essentially replacing one of the wires from the battery with the meter. The mA function of a multimeter would work.

It has a 12v input connector. connect an ammeter in series with the + side of that connector.

The picture of the component is completely inadequate, making it impossible to answer. We need a circuit diagram

We would only need to know WHICH current op is asking about: the total draw, under load, or for some individual component (which is very unlikely).
