Please post your circuit diagram

You'll find it easier to get advice if you first read and follow the advice given to you in "How to use this forum" at the top of every forum. The code posted correct plus a circuit diagram and details of the components you are using would all help as would details of what exactly you see in all those Serial.prints.

Does the fact that you never call the measureBusVoltage() function have anything to do with it?
