DBS Power problems after flat battery

[Astonmartindbs]

hi i came back from UK today to find my Aston Martin DBS manual 2010 with a flat battery, i was able to get in and change the battery as i had the emergency key but like in previous messages i found on here, all electrics worked except for windows, AC system satnav and stereo would not power up from ECU. i didnt even get the red light around the ECU coming on and no matter what i did nothing changed
the only thing on the dash board was a light showing the alarm system operating and the central locking eventually started to work the dashboard only showed the mileage nothing else

as i had put a new battery on i would of thought the power was sorted but it wasn't. there is no battery reset button behind the drivers seat like there was on the DB9 and i was hoping someone would guide me on what may be a fault? or does it reset itself like someone had happen some 12hours after charging their battery via a battery power pack connected into the boot

i am desperate to find a fix for this so anyone who can advise me on what to do, would be appreciated


thanks

Is the battery fitted securely enough - it could be as simple as one of the terminals not sitting correctly - enough draw for the alarm etc but not enough to turn it over etc (easy enough as they're in a fiddly place). Otherwise, pop the trickle charger on overnight and then follow the seat / window resets as needed.

hi Kris

yep all fitted correctly, power is enough to do everything but the ignition via the ECU and the windows don't actually go up and down, they have dropped so as to open the car door but the windows power comes when the ECU key is in so they wont work as yet even with the doors open

the battery is brand new so should be charged.... well you would think so but i will try the trickle plan you suggest,

should a ball ache that these things happen

How long has it been left without being connected to a trickle charger?

Neil - I'm with you, low, despite being new. Easy enough if it's been sat around for a while. Hopefully as easy a fix as it sounds

hi appreciate the comments and advice about the battery power, i have since found that inside the fuse box is a 20 amp fuse which was blown, this fuse is linked to the ECU

i took the car on a low loader to linten automotive in Tenterden Kent which is owned by an ex Aston Martin mechanic and he did a fault finding exercise to the trace the fault and appears to be a failure in the ECU


i just now need to find a replacement part via Aston Martin and then have Linten fit it and see if it requires programming

again thanks all
