As above, non of the internal lights are working at the moment, and drivers seat adjustment (memory seat) is also dead.
Checked likely fuses with no joy, so a bit stuck on what to do next.
Any ideas please ?

[dave the builder]

Have you disturbed the loom plugs/connecters next to the battery ,fitting a battery ?

[Doctor Gollum]

Fuses 5 (30amp) and 15 (20amp).

Otherwise one of the two fuses above the battery. The two nearest the wing.

Anything else not working? Wipers/Climate/cooling fans etc...

[Migv6 le Frog Fan]

Havent disturbed anything for quite some time. Fuses 5 & 15 are ok. Pretty sure everything else is working ok.
Will check the ones near the battery. Thanks.

Does it spring into life when you lock/unlock the car? Or if you disconnect and reconnect battery?  If so, check the continuity of the door switches, esp the fronts.

[Migv6 le Frog Fan]

Havent managed to take a look yet, due to being unable to park it outside the house at the minute. Roadworks & traffic lights that were supposed to last for one day last Weds are still there. Although there isnt actually anyone there doing any work. 
Will try all of the above though when I get to having a look.
Thanks.

Just been out and had a gander. Fuses, including ones above the battery are all ok. Removed all four door switches and checked for continuity, all ok.
Disconnected battery for 10 minutes and it made no difference.
Im stumped.

IIRC there's a timer relay that powers some toys for so long 

[Migv6 le Frog Fan]

That rings a bell. Also the rear aux. socket isnt working either and that runs off a timer. Drivers seat adjustment doesnt though.
I hate electrickery. Its fickin witchcraft. 
Need to find out where that relay is so I can check it. May well have a spare, as I have quite a collection of Omega relays.

sorry , i don't have my haynes joke book here
tried f12 fuse ?   
(20A) Interior lamps, boot lamp, hazard warning, information display, audio unit

Does the passenger electric seat stuff work? Up down, back, forwards etc. Looks like the passenger seat isn't a "memory" seat (lines 3844-3849 on the circuit), and it's only fed from fuse F5. If the passenger seats work, then it's not related to F5.

The memory seat is lines 3800-3842 on the circuit diagram. Fuses involved are F5, F12 and F15. If F15 blows you lose the dashboard instruments - all of them - speedo, rev counter, fuel gauge etc. Since you've not reported that, then we can assume F15 is OK. The memory seat ECU is connected to the diagnostics, so Tech1/2 might (but probably won't!) give you some clues.

So F12. That seems to supply a shedload of stuff, including CID/MID/GID, alarm, and about 20 other things. I suspect you'd notice if they weren't working.

The light switch is S2, on lines 422-449. Does the light in the light switch itself illuminate?

The sunblind lamps are lines 1318-1323. These are driven from the light switch (S2).

The reading lights are E27 and E28 on lines 1220-1247. The consumer delay unit (CSR) is K153 on lines 1327-1340. The consumer delay unit uses fuses F29 and F7.

There is a link between the CSR and the electric seats - traces 1207[TKS], 1306[CSR], 3804[MEM]

So on balance, I'd agree you need to be looking at the CSR - specifically fuses F29 and F7.

[LC0112G]

That rings a bell. Also the rear aux. socket isnt working either and that runs off a timer. Drivers seat adjustment doesnt though.

I think the aux socket is X68, which runs off relay K154, both of which are on lines 1344-1345. The relay is turned on/off by the CSR (K153 lines 1327-1340). Again, that points to fuses F29 and/or F7. If it's not them, then the CSR itself. Dunno where that lives though- it's not a simple relay - it has at least 9 terminals.

A huge thankyou for taking the time to type out all that superb info above.
And it was worthwhile from my point of view. The only one of those fuses I hadnt checked was F7, because the handbook lists "check control" and nothing else for that fuse, so I just ignored it.
Just been out and had a look, and sure enough F7 was blown. Replaced it and now everything that wasnt working, is working again.
Thanks again.

Nice one, Malcolm. Very helpful, as always 

[Migv6 le Frog Fan]

Indeed. 

[LC0112G]

Thing is, fuses usually go pop for a reason, particularly ones that are 20 years old. If it goes again in the near future then you probably do have some other problem.

Can't they just die of old age? Bit like us really.

[Migv6 le Frog Fan]

Will keep an eye on things and keep fingers crossed it isnt a sign of a bigger problem.

Indeed. On Omegas it's usually 5p pieces in the ciggy sockets by the little baskets. Though doubt that's Alb's problem, as he is very old, and I heard his great, great, great, great grandkids were well behaved 

[Migv6 le Frog Fan]

I used to quite like you, a long time ago.
