Just bought me Omega last week and its been running great but went out uo town last night and when I came to come home the battery was completely dead nothing, zilch, nowt. Eventually got into the car by sending a skinny mate through the boot and back seats. Anyway put the jump leads on and fired up no problem, this morning went out to the car and the exact same thing except no skinny mate so had to drag my delicate 19 stone figure through the boot anyway went and ot the battery checked and they said it was knackered so bought a new one fitted it and off I went on my merry way. Parked the car up and went out for a couple of hours and then went to go out in the car... guess what no power, the battery was completely flat agian but fortunatley this time I could open the door with the key. I've been driving the car all week with no problem starting, its always started 1st time everytime. The only thing I can think that I've done different was to park on a council car park which wasn't the best or flattest of car parks ie potholes and divets I'm wondering if I've dislodged something under the bonnet and its shorting out, I can't see anything obvious from the top. Anyone any ideas as to what it could be to drain the battery that quick?  :-/

if you can get hold of a multimeter/volt meter with the engine running you should be getting around 13vs ish, if not the alternator is fubar

if you are the connect a ameter inline off the battery and see if there is a drain on the battery

its clearly not the battery at fault

I agree with the learner mecahnic. i had similar prolem with my diseasal Astra. My problems were dodgy connections to/from alternator & battery.
Chally had a new battery fitted, so it's either a charging problem or a discharge problem or a problem similar to mine in the the alternator is doing it's thing correcty but the chargeisn't reaching the battery.

If a new one was bought then you need to check the voltage to see if the alternator is working, if not then as suggested above you need a new alternator.

get a dc volt meter, u can get a chep one £5. set it to dc volts, connect across the battery with out the engine running, record the reading 12 to 13 volts ish it will read, start the engine  see what it reads now. as u rev the engine the volts should rise if every thing is ok to 13 to 14.5 v dc. if it does  its charging ok , so you fault is something draining it.  if ur in madchester send me a pm c if i can help u out . steve

Yeah I got a new one fitted this mornin got it from a place I've used before on my Vectra so know they're alright. But my thinkin (which isn't always the brightest) is that when I pulled onto the car park last night I could've dislodge a loose + supply to something and its now shorting out on the chassis somewhere. Its gotta be something big to drain a brand new battery that quick wouldn't of thought a dodgy alternater would even do it that quick  :-?

Thanks for the offer mate going to get it in work 2moz and get the front end up a bit so I can crawl/see underneath just to make sure its nowt obvious like a + supply hanging down somewhere and got a meter in there so will try that, but may PM you if I get stuck   ;)

ok hope u sort it
