2021 389 Pete parasitic drain

[B_Beat_CWE]

Dealing with parasitic drain in a '21 389 (x-15) in our fleet and have traced it to a 2 amp fuse in the inside cab panel labeled RDA. Any insight on where to go next?

What is the fuse for? What is "RDA" ?

[B_Beat_CWE]

That is basically what I am asking. should have been more specific. That's what has me stumped. No clue what "RDA" is.

Maybe unplug it and see what stops working?.

Yea I’m with Rawze. I would unplug the fuse and see what stops working, if you can’t find anything not working maybe hook ESA software to it and see if anything is giving a fault code. Also if you can access the back of the fuse panel (if the panel is like the older ones) to see what wires go to the fuse then you can look the wire number up, wire numbers are standard across all makes and models so all you have to do is look up the number and it will tell you what the circuit is for.
