Hello peeps, been a while.
Hope everyone is okay


Omegas been off the road for 9 months and recently been draining the battery down to near enough nothing.
Before I jump in, what number /  which TDU controls the timed tag lighter ?

It's the consumer relay, but off the top of my had I can't remember where it lives

That said, on top of the battery, Fuses 5 and 6, large ones, feed all the interior gubbins, so pulling both of those will kill anything stuck on stone dead.

Just make sure that the key works the tailgate lock for entry purposes

Yeah already found out about the tailgate the hard way.
Battery was down to 4 volts so I’m thinking it’s damp around the
starter / alternator.
Just replaced the battery.   Dash lights okay,  no codes, fuel pump priming,
Just not turning.   Just emptied my WD40 on any electrics underneath and I’m gonna get a hot air gun wafting around underneath later if I get chance

Firstly, once a battery has been allowed to discharge, its oppsed. How oppsed depends on how excellent it was before.

Secondly, WD40 is really bad for electrics, as the oil in it acts as an insulator.  Use a water displacer designed for electrics.

Lastly, consumer relay is up under dash by base of A post

And fourthly, an Omega with a very good battery will completely discharge in around 4 weeks. That's normal.  That's why the dear Lord invented battery maintainers

Mine occasionally discharges its battery in around a week, and I dont why.

Then (assuming the battery is good), that's a fault, and the consumer relay is a bloody good place to start.

I once measured 0.014Amps. Theoretically 0.014*24*30=10Ah in a month if I calculated right (usually not). Then I could guess 4 months instead of 4 weeks but not tested.

Thanks for the replies
Had battery (europarts special) on slow charge all Saturday night and by Sunday morning it would only hold 11 volts so blagged another one under warranty.
Had a quick look this morning before work and voltage hasn’t budged at all but still not turning over.
I’ll get it up in the air and see how many volts I have across the starter solenoid when I get chance / and it’s daylight and let you all know

It’s actually PX24 which we used to use in the military.
Always thought that and WD was the same thing

this is true and even if a once good battery does recharge it will never be as good as it once was.
before changing my (believed good) battery on mine last year the car could happily sit untouched for 2 months and would start fine .after a draining issue later in the year a new one wasfitted and a noticeable difference was observed in starting speed.
mine has now been stood untouched since beggining of sept and will be fine next week when i retax it.
9 months however would definately flatten and damage a good battery.!

If leaving an Omega unused for a few weeks , I either disconnect the negative battery terminal, or just lock it from the driver door button, accessing it via the rear door, therefore not activating the alarm, which, on mine, is the main culprit of the battery drain during a good few weeks of inactivity.

[cam.in.head]

removing neg terminal yes would guarantee no problems but to be honest mine is ok after 2 months easily and so are my classics. my viva can sit untouched for 6 months and start ok but there are no items on that to drain the battery anyway.
batteries are a funny thing.
i bought a few bosch batteries back in the day  and didnt find them to be particularly long lasting. maybee 2 or 3 years max.but strangely enough (and i have absolutely no idea why) i bought a NO NAME / unheard of battery back in the very late 90's and that battery is still alive and well now.
i also have an optima red top that i bought in 2006 for a small fortune that is still alive so that just shows that batteries are a mysterious breed .
i know most of you wont beleive my last two statements and thats ok ,i dont realy beleive it either but its true !

[johnnydog]

I do Chris! I bought a Triumph 2000 in 2010 that had a 096 Drivemaster battery fitted. I have kept the car in several garages since but I never charged the battery in these periods of inactivity (very remiss of me really but the battery is still going strong to this day and is still holding charge and starts the Triumph with no problem. It has an electric clock which is the only physically drain on it, but I certainly can't complain. I don't know who even makes Drivemaster but possibly other example of premium makes not always being better....
Just been to out to check it, and bearing in mind the vehicle hasn't been used for over 6 months, it is still showing it is 90% charged.
