"Don't touch that fuse!" Oh Oh, too late.

Hi, I am a new member and a new owner of a Rover 75 tourer diesel. I am very happy :lol: to find this site and hope I can sort some problems out with your help.
My battery is draining flat if I leave the car for a couple of days. I checked the current flow with "everything switched off" and found a 2.5 to 3 amp flow which I traced to a 50 amp fuse in the engine compartment fuse box. It is not an ordinary plug in fuse. It is one of the fuses held in with two screws. The diagram on the cover of the fuse box just has a picture of an engine for that fuse.
The owners manual calls those fuses "fusible links" and says nothing more about them other than advising owners not to touch them and leave it to a qualified electrician.

Ooops! In my enthusiasm to find the power leak I removed each fuse, one at a time and tested with an amp meter. I have removed the 50amp fuse for a couple of days to see if the battery will be ok when I put the fuse back.
Can anyone tell me what the fuse does?

Can anyone help me with a wiring diagram? I read threads here that suggest the Haynes diagram is not much good. Any advice would be most welcome.

Hi, thanks for the reply. It is fuse FL3 and yes I have a sat nav, TV, cd changer and alarm. All of which I suspect as possible causes.
Do you have a suggestion for the power draw?
Thanks

First check.....open the tailgate and look at the satnav computer. The red light should go out after 30 seconds or so. Don't touch anything else as you'll start the shut down cycle again.

I'm not a million miles from you, if you want to pop over at some point, I'll gladly take a look

PS
There is a space for a FL5 fuse but there was nothing in it. The box diagram shows a profile picture of a car (4x4 range rover?) with two arrows pointing up and down by the tail gate. Seems a bit large for a boot release fuse. Not sure what that is for or if I need a fuse there or not.

FL5 is not required

I have no idea where the sat nav computer is. I will check in the morning. Also I would be very pleased to drive over to you. I will try and send you a PM with my phone number if that is ok with you.
