So just to confirm - pulling Fuse 20 does not stop the fusebox in the drivers footwell from working? Is that correct? And if the answer to that is yes, what initially made you think that it did and why have we been pulling our hair out trying to think of reasons as to why that should be?
It was a few week back when i was trying to figure out things,it was freezing cold and damp.I was tired,my old bones was hurting some what.I must have just turned the key one click and saw no ign lights,tried my sun roof and windows then put the fuse back in.Human error,and i do appologise.I was just thinking the worst,i always do.Sorry.

From the list of fuses, the first one, Fuse No.18, labelled 'Radio No.1' and rated at 20A, is for the radio/CD so I would guess that this is the main 'working' fuse for the radio.
Fuse No.20, the 'Dome' fuse feeds, amongst other things, the interior 'dome' light, the ignition switch light and the radio/CD.
Because the ignition switch light only has one purpose in life - to allow you to see where to insert the ignition key when it's dark - it must have a permanently 'live' supply to do that, so I would hazard a guess that Fuse 20's connection to the radio/CD is to keep the radio presets in memory while the ignition is off.
If I'm correct in my assumption that Fuse 20 provides a permanent live feed, then with the radio disconnected but the fuse still in circuit, everything else it feeds such as the interior light, the ignition switch light light etc., should still work.
But none of that answers why, when Cliff pulls Fuse 20, does everything in the drivers footwell fusebox go off?
Good news,when i pull number 20 fuse most things still work.the things that don't work are.dome lightes,door lightes,glove box light,ign switch light,centeral locking and steering wheel.motors.It' got to be one of them that drains my Battery.It could be something to do with remote locking,i haven't got a remote key so i can't test that.

Zooming in on the right-hand side you can just about make out the number 89570-50010, so Googling for that shows that it's the fuel pump ECU:
Thanks Herbie,now i know what it is.

Cliff, you say that when you pull fuse No. 20, the Dome fuse, rated at 15A (which should only be 10A), it stops the battery drain. That's good as it gives something to work with.
However, you also say that it stops everything in the driver's footwell fusebox from working. That's bad because fuse 20 has got nothing to do with the fusebox in the drivers footwell.
None of the items listed above from the pdf document you uploaded, tally with the items listed on the fusebox cover from the drivers footwell below, so the Dome fuse can't have a bearing on them:
Something is wrong somewhere and if pulling the Dome fuse really does stop everything in that fusebox working then it's going to be difficult to sort out.5 hours ago, Herbie said:The word 'Dome' usually refers to the dome light, the overhead light that comes on when you open doors, rather than a description of the fuse itself, as you'll see from this:
It is a blade fuse,number 20-dome,it had a 15 amp in there but iv'e put a 10 amp in now.The ign light is on the list,if the fuse knocks the ign off then nothing will work..i'll have another go in the morning.Iv'e got head ache and brain freeze.

Look at this silver thing above my cd player,when i unplug it my engine stops,anyone know what it is.

Did you establish that your CD player in the boot opens?
Its a permanent "live" and if it isn't working then you need to check the cable routing.
Is it a 15 A fuse to the Fusebox? Seems low to me as Heater is 20A? Doesn't answer your drain problem given what you say.
No the cd player doesent open,i presumed it was because the radio doesent work.All the fuses are ok.I think your right,this is where the problem is.

Hears the deal,when i pull the 15amp dome fuse out of the main fuse box the drain stops.That's the fuse that runs everything in the small fuse box under the drivers footwell,i pulled every fuse out and guess what.The drains still there,the car is usable and great to drive.

Should be fun. Hope the new fuse box does the trick. I'd check all the earth points in the engine bay before installing the new fuse box.
I'm not swaping the full fuse box,that would be madness.I only bought a spare fuse box for the innerds,it was worth £15 quid for all the relays and fuses.

Where are you with your project?Hi.Iv'e not touched it for a while,the weathere's been a bit damp and my bones have been aching a bit.I connected the battery this morning,first turn of the key and away it went.I'll be back on it in the morning,iv'e replaced the dodgy altinator fuse and swapped all the relays out of my spare fuse box.The batt drain is still there thou,i'm thinking of fitting a battery cut off switch if i can't sort the drain out.

I think it's best to get yourself a whole newish fuse box, may be from someone who's breaking an Ls because that looks bad
That's what iv'e done,it should arrive tomorrow or saturday.

If that jumper clamp with the red wire is the supply to the fuse box then I'd stop buying stuff piecemeal and start taking bits off for examination (like the fuse box, alternator and the linked wiring harness) until I see a clean base from where to start rebuilding. Interesting project if the mechanical side is sound. But not an afternoon job. (Not even a weekend job). Fun for an enthusiast.
It's my project car,it's got 11 month mot.The engine is sweet with only 100,040 miles.it's taxed,insured fully comp for £175.00.Sweet.

I was looking at your Photo and thought I hadn't seen Lucas Batteries for quite a while. (maybe I've not been looking).
Then I read that Yuasa stopped selling them to Lucas in 2006. I also saw this Lucas Battery but upon reading it is for a Start/stop vehicle and seems they sell them more for Mobility Scooters. Is it suited to a Lexus LS400??Does it say manufacture date 2011 Perhaps its not the one you have??
Also did you take each fuse out and test them for continuity as they all seem to not have their cover caps in place or perhaps I just can't see them?
I bought that Battery from a propper car assesory shop just a few days ago,i told the owner what car it was for and thats the Battery he gave me.The fuses,yes two cover caps are missing.My used fuse box might arrive satureday,it's got everything in it so i'm gonna do a swap on everything.See what gives.PS,i will check the Battery tomorrow,if iv'e been sold a dodgy Battery i will play holy f..k with him.

No Cliff, the red wire is a disaster waiting to happen and it may already be affecting something you can't see, but hey-ho, I wish you well my friend and I hope you get it sorted soon.
Ive bought a used fuse box with everything in it,we can only see what happens when i fix that botch job.I'ill keep you informed,i'm optimistic on this issue,got to be.

Aren't you the one trying to find a parasitic drain that keeps flattening the battery?
Again, aren't you the one with the electrical problems? How do you know "everything's fine"?
A fuse is meant to be the weakest link in the chain and it's meant to protect the wiring by blowing and disconnecting the circuit in case of excessive current. If excess current flows and the wires upstream can't handle it, the fuse should blow to protect them. Because there's no fuse there but just a lump of wire instead, the wires upstream may have got hot, the insulation may have melted and the conductor touching an adjoining conductor could be causing the parasitic drain.
The pink fuse holder below the dodgy one is showing signs of melting if I'm not mistaken.
Everything works exept the radio,the car runs and drives fine.Iv'e read the ls400 is protedted againsed putting the Battery on the wrong way round,the last owner did just that,the red wire is an emergency repair.I will find and fix fhe problem,i never give in,personaly don't think its anything drastic.If i can save this car i will do.Ive seen nicer looking ls400 scrapped,broken just for parts.It's a shame.ps,i did have to fit a new altinator.

Wow Cliff, I'm sorry to say it but it looks very much like you've been sold a pig in a poke there mate. It's no wonder you're having electrical problems and I think I now understand why your auto-electrician said he couldn't help!
That bit of wire instead of a fuse could have caused untold problems. You have my sympathy and my sincere best wishes, but I'm afraid all bets are off.
That wire was put on as an emergency fix,everything works fine.They did blow the altinator and the radio,the car runs fine and all the electrics work.It cant be that bad,i don't think.PS touch wood.

Can anyone tell me what sort of fuse fits here,the last owner blew it,he connected the Battery the wrong way round.He also blew the altinator oh and the radio.i put the arrow in the wrong place,it's the fuse with the botch up red wire across it.cheers

We've had a pm conversation about the Radio not working and you tell me that the Disc Changer in the boot doesn't open.
As the disc changer opens without the key in the ignition, I suggest that having already removed the Radio once, after re-charging your battery you leave the Radio disconnected a couple of days to see if your battery still runs down.
To use the radio, the ignition needs to be at ACC, however there is power to the Disc Changer in the boot at all times and I'm assuming (maybe wrongly? ) that the power goes via the Radio loom?
By doing this you should eliminate all other possibilities than Radio and Disc Changer as your drain.
Entirely your decision to do this, of course.

I think the cd changer gets it's power from the radio,power conector in for the radio,and a conector for power out to the cd player.The radio is kaput,if you still want to sell me your spare radio that would be good,i understand if you don't want to sell it.cheers.

Should the electric seat and electric seat belt adjusters still work with the ign switch off,mine work with the ign off.cheers.

Well lads,an auto electrician couldn't fix my car.Never mind,i'll fix it myself.

@lazzlo amundo Cliff, I like to help people when I can. I don't have a lot of knowledge but I will openly share what I have with anyone at any time if it's helpful.
Please believe me when I say that I do not wish to cause you any offence and I say this with the greatest of respect. I have a back injury that was bad enough to get me medically retired from a job I loved, so you have my sympathy with regards to your health and your ability to get down to the fuse boxes etc.
However, if you can't do it, then why are we spending time guiding and directing you - why not just take it to an auto-electrician who'll get it sorted for you?
I know your right,i just hate not being able to do things myself.I just don't want to admit i can no longer do the things i could do,i don't want to be charged a fortune to be told it'll cost a fortune to fix.Bought with 11 month mot,so far new altinator £148.00 fitted by me,new Battery £60 quid,gonna have to fit a timing belt kit for piece of mind £150 quid.i just expected to be driving it.But yes,i know both you and Tulpin are right.
