Alright chaps after a bit of advice as this is driving me crazy lol the mrs has a 2008 reg 1.25 fiesta mk6 climate and every now and then she will come out in the morning and it won't start due to the battery being completely dead but once jumped its fine again I replaced the battery as I thought that was at fault and had ye alternator tested and it's fine aswell so only other thing I can think of is there is something draining it over night I've checked all interior lights etc but can't find anythin and it doesnt do it all the time just every 2-3 weeks it's booked into a auto electrician on Tuesday but thought I would ask on here as most of you are pretty clued up

Have you checked the boot light?

It all depends on your electrical knowledge, as to what you can do yourself.

You need an Ammeter or multimeter, and you need to connect this in line (Series), in other words between the battery earth lead and terminal, you can then see what draw you are getting, WAIT around 20-30 seconds before noting the reading, as when the connection is remade ECU'S etc will power up and it will take then a while for them to go back to 'sleep'.

If it's anything other than an expected 'parasitic drain' then remove fuses one by one until the reading drops then you can troubleshoot the problem circuit.
