Hi All
I have a current drain on fuse 7 which is drawing 2.4 amps Quiescent (standing) when I remove F7 the Quiescent drops to 0.2ma
I have checked http://www.omegaowners.com/forum/YaBB.pl?num=1161602010 to see what this fuse is controlling but it dose not control the Electrically operated windows. In the Vauxhall manual F7 controls the Check control ,engine oil level & Courtesy lamp. when I remove F7 my Courtesy lamp goes off so I think that my F7 is wired the Vauxhall manual way. Can anyone tell me where to start looking first for this fault
-
Consumer delay unit - quite common
-
Fuse #7 powers the accessory delay timer which in turn controls the courtesey lights, along with rear 12V socket relay.. If this has failed the lights on the window switches will be permanently illuminated and the rear 12V socket will be permanently live
-
Check the things that hand off the Consumer Delay Unit... ...bear in mind this will be active for 15mins after key comes out of ignition
-
Thanks TheBoy
For the quick reply where will I find the Consumer delay unit

From memory up above pedalbox

Thanks RobG
I will check once the battery is charged and I put it back on :y

Hi Guys
I done a quick test I put the battery back on and Fuse 7 back in and left glove box open and phone chager in rear 12V socket. Locked the car up and after about 5min they both turned off after a click from under the pedal box think the click was from the Consumer delay unit.The lights on the window switches turned off when I locked the the car.
If its not the Consumer delay unit what else could it be. There is also another fault the spanner light also comes on and a little while after the engine cuts out the code reader said crankshaft sensor I changed it twice last week and cleared all codes but it still comes back. Dealer said they both maybe faulty and has ordered me another one.Could this fault also be related to the battery drain.

The only thing I can see that's fed from F7 other than the delay relay is the "Control unit - Minimum capacity, engine oil".
Anyone have any idea where this is located? Seems an unlikely cause of excessive current drain, but might be worth unplugging?

Presumably with a battery drain problem, the powersounder has been unplugged and eliminated before delving too far into the fusebox ?
:-?

yeah, its on a 2.2dti :P ;D

alarm has connections to consumer delay, might be worth unplugging powersounder

Hi All
I think that i have found the problem a big yellow relay above peddle box part number 24427610 12v 38697 this was on permanently when I unplug it I have no drain on battery only thing is that I now have no courtesy lamps or 12v rear socket. should this relay be on permanently
-
That sounds like the consumer delay relay.
Question is: Is it defective itself, or is something triggering it?
-
Hi All
Thanks for all your help changed the relay last night and put fully charged battery on last night checked this morning and throughout the day and its only drawing 0.49 Amp's with all fuse's in will keep an eye on it.
Thanks again
-
Next job for you -
Check your meter !! 0.49A is far too high, and would drain a battery - should be around the 50~70 mA or so, not approaching 500mA.
The next few days will tell - if your battery remains fully charged, then your meter is innaccurate
::)

Agreed. I'm starting to wonder if it's reading 49mA, which is nothing to worry about. :y

Hi Guys
Thanks again for the help this is how I got my reading I set the meter to 10A on the dial and got the reading of 0.49 so would that be mA .
So do I have anything to worry about ? ::)
-
If you got a reading of 0.49 when on the 10A range, that is 490mA (which is way too high).
-
Thanks
Well started at 2.4 so am getting there looks like Ill be pulling circuits this weekend. :'(
Any advice on where to start :-?

Start at F1 and work your way through.

Thanks Martin
Done that Fuses 6 & 7 seem to be the the problem

Don't have a manual so I can't help you with what is fed by those fuses, I'm sure someone else can though.

Thanks for that Andy.
Denisaok,
There isn't much on those 2 circuits, and if I had to pick what to blame first, I'd be looking at the radio (F6).
What does the quiescent current drop to with F6 only removed?
PS
I take it you have checked that your meter is telling the truth to start with?
-
I would advise that a 10A setting on a meter is not going to be sensitive enough to measure accurately a small reading of 50mA
I would obtain another meter before going any further

Pretty much all the "diy" DMM's will struggle with reading 50mA or so on the 10A range, but if the OP gets a reading of zero (or near) after seeing 490mA then that will be enough to show them they are on the right track.
One thing I would do though is verify the accuracy of the DMM as you suggested earlier, the cheap ones do produce some weird & wonderful "results" when the battery starts to get low (such as over reading).

Hi All
I will use my mates meter his a TV engineer an coming to give me a hand on Saturday. I got a tis 2000 today to help trace circuits will keep you posted
-
Hi all
All sorted now turned out that the 1st delay relay I tried was faulty to.
