My problem is a bit different and hoping you could help me out with your knowledge. 2011 Honda CRv, we found that the battery draw is coming from under the hood fuse socket # 23, "Back Up". It is a 10A fuse. Drawing about .265 and draining the battery in about 17 hours. Be grateful for some help.

 

welcome to the forum, if it is back up light, you might replace the bulbs. if it is the back up camera, might check for good ground and wire ware into another, usually where the hatch opens and closes or at the connections. only experience I have had with a small draw like you have was a dead light bulb, drawing voltage not working, killed my battery also after a long time sitting.

 

I haven't worked on a car as new as yours, but isn't the Back Up circuit supposed to be powered only when the car is switched on? If so (whick would be my hunch) I would look for whatever short circuit might be giving that circuit power when the car is off.
