I was having trouble measuring current in a running sketch using an INA226.
To troubleshoot I bought a new Arduino Nano and a new INA226 breakout board.
I used Rob Tillaert’s demo sketch from GItHub verbatim. It compiled and uploaded fine.
I powered the nano by USB to my PC, running the IDE
I powered the INA 226 with its Vcc connected to the 5V pin of the nano and its GND connected to the GND of the nano.
I connected SDA of the INA226 to A4 and the SCL of the INA226 to pin A5 of the nano.
I got no current readings with in+ and in- connected to active shunt. I tried powering the INA 226 from 3.3 pin and still no connection.
So, I loaded an I2C scanner sketch onto the nano and it runs but finds no devices at any address.
I tried a UNO and a different (new) INA 226 breakout board.
All hardware is new and, I think it is correctly wired.
Any suggestions?

The most common reason is that SDA and SCL are swapped. If that isn't it, post the code and the verbose upload log both in code tags and a photo of a hand-drawn wiring diagram. Label any non-obvious parts.

Here is the sketch:
#include <Wire.h>
void setup() {
Wire.begin();
Serial.begin(9600);
while (!Serial); // Wait for Serial Monitor to open (for boards like Leonardo)
Serial.println("I2C Scanner");
}
void loop() {
byte error, address;
int count = 0;
Serial.println("Scanning...");
for (address = 1; address < 127; address++) {
Wire.beginTransmission(address);
error = Wire.endTransmission();
if (error == 0) {
Serial.print("I2C device found at address 0x");
if (address < 16)
Serial.print("0");
Serial.print(address, HEX);
Serial.println(" !");
count++;
} else if (error == 4) {
Serial.print("Unknown error at address 0x");
if (address < 16)
Serial.print("0");
Serial.println(address, HEX);
}
}
if (count == 0)
Serial.println("No I2C devices found\n");
else
Serial.println("Scan complete\n");
delay(5000); // Wait 5 seconds before next scan
}
2) Here is the verbose output for upload:

That resistor (shunt) is going to burn up quickly, no?
I was trying to figure that bit of the schematic out myself. And yes, if the negative side of the battery is connected to ground as well, the shunt on the INA226 is going to be glowing in short order.
OP: the INA226 is supposed to be in series with the load, not in parallel.
Edit: the shunt resistor is in the INA226 itself? And can handle up to 15A? Colour me impressed.

Sorry guys. The shunt is a low side shut on the battery ground, measuring the charging current, net of loads. Loads come off the (not shown) positive side of the battery. Also, the shunt is 0.0001 ohms not 0.001 as written. Don’t think that changes anything.
As shown, it's not - as shown, it's a short from battery + to GND.
