Have an issue with the battery being drained over a period of a couple of days.  Run the car every day, OK.  Leave it a few days - completely dead.

Put a multimeter on and its drawing 0.6amps, whilst switched off and unlocked (i.e. alarm not on).

As I have no idea on electrics, is such a draw on the battery normal for omega (I believe not, but thought I had better check). If not anyone got an idea on where to start.

First idea is to pull fuses to see when the drain stops which I'll do in a few minutes  - after that I'm coming to end end of my very limited knowledge and I'll have to contact an auto electrician, but thought I would check for any ideas first.

thanks

do you have an aftermarket cd player/dvd with screen?

[Kevin Wood]

There is a time delay relay which keeps some things on for a few minutes after switch-off. Might be worth waiting for this to time-out, then the best course of action is probably to remove the fuses one at a time to see if you can identify a circuit that's drawing the current.

Thanks for the feedback so far.  Tried trying to pull fuses to check where it may be, but didn't see any difference in the load.

It does have an after market CD player, but no screen or anything, it is a N reg omega, so I'm afraid there is no new ICE in it.

Still I have taken the 'check coolant' sensor offline as its driven me nuts over the last few months, while I wait for VX to deliver a new header tank -ordered today. Hopefully just bridging the wires wont cause any probs there.

I've also got to the limit of my electrical knowledge and have called in an auto-electrician.  I just need to make sure use the miggy every day so the battery does not go flat - which is not an issue as I love driving it  .

I'll post what we find and what fixes the issue once we get to the bottom of it.

Thanks all.

I assume its not just a knackered battery

Pull the radio and check the load current.

Its always a favourite for people to get the radio live and ign the wrong way round on aftermarket units, and can be undetectable by pulling single fuses.

Drain often comes from powering up the aerial booster constantly.

If so, check live and ign are the correct way round.

There's a light in the boot, have you checked that :question

[Entwood]

I drained my battery 3 times in the early days of owning the miggy ... I didn't know that leaving the indicator in either position turned on the side lights on that side once the key was withdrawn

[Kevin Wood]

If you can't find anything else, I have seen alternators fail where one of the rectifier diodes gets leaky and they draw a little current when stopped.

If you can't locate a fused circuit that's draining, see if it's going down the cable to the starter / alternator.

you beat me to it! happened in my old calibra with a HU i didnt install, took me ages to find the cause!

Had the same problem, kept charging the battery still went dead?

Took the fuses out, to find out what is was draining the battey.

I the end  changed the battery fo a new VX GO battery.

Problem solved.

But I don't want you to buy a new battery and waste you ££££

[Alan]

Just thought I'd update you on the findings.

I had bought a new battery a month ago, as a first try, with no success.  The auto electrician has now been and identified the problem as the powersounder. His view is the battery in it is drawing continual high current and draining the battery.  It seemed to me this is something he has come across before as it didn't seem to be an unusual problem. He has disconected to powersounder and I'll see if that cures it.  If so I can either leave it disconnected or buy a new one.  Haven't decided yet, but suspect if thats cured it I'll just leave it.
Also got new header tank and sensor , so I now no longer get the annoying check coolent level message - harrah  

Thanks for all your ideas.  really appreciated them  Thanks to you all.

Regards

I would imagine that it's gone the same way as mine did. Conductive goo leaked out of the battery and in this case it's causing leakage from the 12v permanent supply. It isn't fused either (except by one of the 80A PDS fuses on later models) which is why it was hard to find.

oh dear not good

i would suggest checking the alternator before buying a batery which we didnt and now 100 quid less which shouldnt have been spent.

Lost the damned Halford reciept
