Hi again folks, I have another development in the overnight discharging battery saga, there are two large bolt together connectors in the engine compartment drivers side, I believe the rear one relates to the fuel shut off loom but dont know what the front one relates to, anyway disconnecting the front one of the two results in the current drain problem dissappearing completely so the issue seems to be with this part of the wiring, does anyone know which components are related to this connector as I am struggling to decipher the scorps wiring diagrams. Thanks.

Where are these connectors?. Do you mean the ones on the inner wing either side of the power steering reservoir?. 
This diagram and chart may help. C110/C112 There is also the large connector to the ABS controller?.
Looking back to page 1 you mention the injectors and if you look at the diagram which Mike H suggested C110 features in that circuit?.
A further thought.Is there any sign of power steering fluid leaking on to the connectors?. If so separating the connector and giving them/it a good clean may sort the problem

Ok folks, made some progress today, rev counter issue has been tracked down to a general earthing problem and resolved, I am fairly sure I have cured the battery discharging issue as well by methodically replacing relays and cleaning connections and fuseboxes, (will wait till tomorrow morning to find out for sure), but using my multimeter as before, the current drain from the battery with everything shut down is now only about 70mA.

Oh well! how WRONG was I! Battery discharging issue is still here, Aaaargh! It is the fuel pump relay circuit that seems to be the cause this time, pulling it out stops the current drain immediately, I can hear it click off as I remove it from the circuit. This with the ignition off, keys out and everything else shut down,

Still appears to keep coming back to damp in the fusebox(es) causing shorts and tracking. And possibly wiring elsewhere ~ 70mA is still not low enough IMO; well a relay coil could account for much of that, yes.

PS: all this rain and damp we've been having lately won't help at all so I wouldn't be too overly surprised TBH

I'm starting to think it is an earthing issue after looking at the grounding diagrams pdf's as the faults all seem to be related to a particular grounding point, the main repeating issue seems to be the green fan relay behind the headlight as it has started to click frantically when the battery is reconnected, unplugging it solves this and seems to prevent any other relays associated with the fault such as the fuel pump relay from actuating as well, also it stops the current drain too. And as I discovered the rev counter fault was ground based, (solved by cleaning the two earth wires that bolt to the bodywork behind the n/s headlight) I think my next checks should be the various earthing points under the bonnet, I may try to strip the fan relay too.

Well folks, the battery discharge problem is solved, it was related to the cooling fan circuit and the green relay behind the headlight, I still have not resolved why this is causing the problem yet but after checking and cleaning all the accessible earthing pionts on the car and completely removing the relay from circuiit all is well again. The mystery I have to solve is that when the relay is reconnected it triggers the fuel pump relay and causes the cooling fans to run very slowly as well, this is with the ignition off or on, dismantling the relay shows nothing obviously wrong with it though. I should have suspected something when I first noticed the relay connector was not locked in but just sitting partly in its recess in the relay, (perhaps an issue for the previous owner?) anyway it was after I had fitted the connector properly that the problems began showing up. I will find the full solution eventually as I now know which circuit and wiring colours to work through and will let everyone know the outcome. The car seems to run quite happily without the fans and with no signs of overheating in any driving conditions. Thanks for all the help and advice so far.

The only thing that I can think of which may help is the route of the wiring. IIRC from many moons ago there can be 'issue' with the wiring which runs across the car from offside to nearside near the radiator etc. If the wiring to the relay seems to come from that area I'd have a look in that vicinity.

Well Mike, it seems you were right about the funny wiring, my scorp started acting wierd again on wednesday night, then wierder on thursday and finally became undriveable on friday, (misfiring, cutting out, smoking exhaust etc) so I decided to investigate the loom along the front of the engine and along the n/s wing. Along the front was all good but along the n/s wing! WHAT A MESS!! insulation broken away on all the signal leads and many others, one main power feed wire completely broken and some others just hanging by a thread, also looks like water-antifreeze mix had got in at some point from the heater hose, (not while I've owned her though) so that explains the discharge problem I've been having. Anyway after a 12 hour loom rewiring and repair marathon yesterday, lots of new cable, soldering and heat shrink tube, grazed knuckles and an aching back, she is now running properly again, fans and rev counter working as they should, and no battery discharging either. I just hope thats the end of this saga at long last.

Hi again all, thought I would just let everyone know that since my marathon rewiring session on the main loom my scorp is still behaving itself perfectly, it hasn't missed a beat, all electrical systems are working better than ever since I've owned her, (I bought her on ebay for the princely sum of £56 six years ago ), so it seems like the loom damage had also been part of the various electrical gremlins that have come and gone over that time. Economy has improved dramatically as well about town, and she is much smoother and also very much perkier in the acceleration department too. I really dont think I would have persevered with this problem without the help and advice of all you great people on this site, so a very big thank you to you all from me. Also many thanks to Leewar for posting a fuel shut off loom out to me even before I had paid him for it.
