Battery Keeps Going Flat
Posted 03 March 2013 - 09:08 AM
Would really appreciate if anyone can shed light on this problem for me as I am a letting agent and need my car for work so it has really been an issue and I just want it sorted

Take the battery cover off and make sure that the ring around the electrode is firmly held in and is sat at the bottom of the electrode (top of the battery).
At the top of the electrode (between the top of the ring and the top of the electrode) there should be about a 1mm gap on both positive and negative.
Could be something as simple as that...

hmmm, the ticking indicates a low voltage, whats the voltage of the battery when the cars not running?

trust me just because the guy said the battery was ok doesnt mean its not a lead acid battery it must be calcium or silver calcium so as always its best to start at the battery make sure its the correct type a lead acid battery will not charge properly cause many issues electrical mainly so far the majority points to incorrect alternator fitted or a faulty smart charge posibly a broken 3 pin wire on the alternator when they replaced it or the battery no offence but the aa have stuffed a lead acid battery in cars that shouldnt have them before so i wouldnt take there word for it

like arcscot said, make sure you have the correct silver calcium battery especially for a diesel.
and i'd highly invest in a multimeter so you can get a reading of the battery voltage.
Also check how much oil you actually have in the engine? is it below minimum or overfilled?

There's a lot of questionable things from your replies though, almost implies the garage your taking it to are fobbing you off.
Sealing an oil filter doesn't help with air getting into the system, unless they meant fuel filter.
Disconnecting a radio is a joke in my opinion. Never ever heard of a radio coming on by its own, let alone leaving you with it disconnected like that.
I would go back to the service receipt they gave you and list exactly what they did to the car. As has been posted, glow plug relays are known to cause battery drain faults, but I'd also be suspecting something on the glow plug rail either not being connected properly or something.

have to agree the radio has a 1 hour mode so it cant come back on on its own unless theres a serios wiring fault it does sound like the garage dont have a clue given the problems started after you took it there ide say that was the case

Check the running battery charge with a multi meter, if its over 14 the alternator is alright, and engine off the battery should read 12.6, im not sure if the alternator on these have the test posts on the unit its self, im sure there is also a way to check the battery voltage with the trip computer, but im not sure how you unlock it on the focus, maybe someone else does then you could let the onboard diagnostics run see if that throws a bone. Good luck.

follow the dash trick as that shows you the reported voltage. Between that and the likes of Torque Pro, I have seen the voltage to be pretty much bang on to what a multimeter shows.
