Battery draining overnight

[farghi]

Good evening All.. I have an issue with battery drain.
I've fitted new alternator
fitted new battery
Now alternator charges battery at 14.7 volts
Overnight the battery has discharged
Removed negative feed from battery connected ammeter to negative lead and now removed negative battery lead
With nothing turned on ignition off reading 10.7 amp draw!
Removed fuses from aux fuse box in engine bay it's the green 3rd fuse down causing draw it's rated at 30 amps.
I cannot find a fuse diagram or circuit diagram to trace further the culprit chasing the problem
Any advice gratefully received

3rd fuse down should be fuse 3, 30 amp, if it is its the feeds for fuses 31, 33, 46, 59 & 63 in the interior fuse box

Looks like its going to be, if fitted, a central locking problem, trailer socket or audio as fuses 33 and 59 are only 7.5 amp

Thank you very much, I'll now isolate those big amp user fuses! Let's see what happens! Will let you know!

OK festivities over I've dived into the fuses with a new multimeter. 1.3 amp draw on test.
Two fuses on board behind glove box indicated on the photo below .2 amp and .7 amp draw.
The larger draw was from the audio unit
Now this has been salvaged from and old Mondeo it's the Sony single cd disc model
Had been working fine but for some reason it draws .7amp on standby ...could be wiring is different to Transit Connect. There is no cd stuck in mechanism.

So any ideas/thoughts I could try?

what number fuses are they, the pic's a bit crap, 700ma is far to much, did you pull the fuse for the audio or disconnect the unit? have you checked the central locking? I think fuse 63

Thanks for the reply, I disconnected the audio unit. There doesn't appear to be numbers on my fuse board or cover. The picture shown is of the fuse panel behind the glove box

Do you have a number schematic of the fuse box?

I forgot to mention I removed 30 amp fuse in main under bonnet fuse board. Battery drained overnight. So now totally confused. This was the fuse on which there was the big drain!

They can drain back to earth, through a faulty alternator regulator diode. Try unplugging the alternator overnight and see if it still drains

I know it might be silly, but do you have mice/rats kicking about where you live? They can chew the wires and cause direct shorts somewhere along the loom.

Hello,

I also have trouble with battery draining overnight, I did parasitic test and checked that too much power is going to fuse F48 7,5A. Can someone tell me for which thing is that fuse?
