Right guys cars running fine had flat battery I put new one in leave it over night and battery in morning is flat tired new battery same thing seems to be draining over night any thoughts

[starletezy]

sounds like your alternator might not be charging the battery

[ashep91]

It's a new battery I don't drive the car just put in new battery and leave it over night when I come back in the morning the new battery just goes flat

[StuDoc 72]

Do you have an amp fitted to the car?

[Ollieh17]

Multimeter on the battery and take fuses out one by one should point you in the direction of whats draining it

[ashep91]

No amp fitted no cd player only Apexi power afc with hand commander aem wide band and 6 gauges it was fine last year seems to have happened all of a sudden and I haven't added anything

[ashep91]

I had a battery from this new place thought it was that they swapped the battery for a new one same thing could it be a bad batch of batteries?

This

Thanks guys will give it a go and keep you posted just before I try though could it be a earth somewhere or a faulty ecu? Although it as running fine last year

Also I can't see gauges running a full battery down over night

[morgey]

If the battery is flat no, if its just struggling to start but the battery is charged then possibly

It could be a power lead earthing out, That would drain the battery but that should blow a fuse.

[ashep91]

It's just flat no lights hazards nothing that's after I put a new battery in and left it over night when I put new battery in it starts first time it's just after its left over night in l morning it's flat

Alarm systems can be a common cause for a drain on a battery if you have one fitted?

[starletezy]

Would start by using a multimeter to see it its charging first if all good check the battery is not dead

[MARC MOSS]

i bet alternator.... you need a clamp meter or multimeter that can read amps that or charge the battery then remove the plug and pos cable off of the alternator then see if it starts the next day...

Its going to be quite a major electrical component to suck a battery dry overnight and i bet its the alternator as well.....

[ashep91]

Would it still stuck power if car isn't running?

[ashep91]

I do have a alarm system fitted but had it for a while never had a problem with it before I have a viper alarm

[starletezy]

Don't think the alarm would be the corporate if you have no issues with it would be more like battery or alternator

[MARC MOSS]

Would it still stuck power if car isn't running?

Yep all switched off as its a direct un switched link to the battery

[ashep91]
