#1

My Civic has a parasitic draw coming from fuse #29 the backup fuse. Dealership doesn’t seem very knowledgeable any advice on how to find out where the drain is coming from?


#2

That appears to be the fuse for the back up lights. Assuming you don’t have an aftermarket alarm or remote start installed, I would focus on the wiring to the transmission shifter. Without having access to a wiring diagram, I would imagine putting the car into reverse should be the only way that circuit is complete. There might be a specific switch used or it could be the shifter itself.


#3

You have 2 fuse boxes, both with a 19 fuse, the 19 under the hood is for the backup lights, replace the bulbs easy try #1. 29 in the cabin is acc fuse, figure out which one first, my guess the acc fuse, here is a helpful site. https://www.popularmechanics.com/cars/car-technology/a5859/how-to-stop-car-battery-drains/
