2005 Hatch 2.0 petrol auto.
As the title says....Battery goes flat in less than a week.
Last winter the battery kept going flat.
Bought a new one and all was well.
The alternator cooked at the end of last summer. Literally.
I fitted a used alternator and all was well.
Since the weather got colder the battery flat issue returned.
Got the battery swapped under the 5yr warranty.
2 weeks later and dead battery.
The car is only used 2-3 times a week at most. But that's enough to avoid the problem
If it's left for a week it's flat.
Tomorrow I'll stick the ammeter in the supply lines and see if I can tell where the power drain is but wondered if you guy's could tell me the likely causes / suspects.
And... although I'm sure the alternator is doing it's job of charging, could it also be the source of the drain?
Cheers for any advise.
