On my Discovery normal drain has been below 50milliamps.
While replacing a leaking oil filter I checked the battery and was surprised it was low at 11.5 volts, so checked the drain with a clamp meter and it was 0.4amps.
Then discovered it was only the 0.4amps up until the 1st earth point when it leaves the battery, please see picture.Its this figure to the right of the flat connector bolted down to the chassis and another wire is connected here and i think from looking at the wiring diagram this is the SLS system.
SLS seems to be working normal.Double checked with a multimeter in line and drain was same.
This area has 3 earth points on a bit of chassis rail.
On the other side of this flat connector( L.H looking at picture) the drain is 0.02amps which is about right for my Disco.
I spent a long time checking wires i could find underneath and under bonnet for any drain and found none.The cold got the better of me after 2 hours of this.
I am stumped as to why current drain goes to this point, yet beyond it returns to normal.
Any help would be much appreciated.I thought about disconnecting the earth point completely where this happens .Probably not a good idea.?
