    Default 207 electrical issues

    My 2007 207GT has recently developed an electrical problem (yeah, big surprise, huh?)...I have changed the battery, come out the next morning and nothing...no dash lights, nothing...power is obviously being drained somewhere...I hardly drive it, so can't think of any reason why it would suddenly develop such a problem...any ideas?

    Try unhooking the alternator to battery cable.

    Alternator diodes occasionally fail.

    yes, was my first point of call, but alternator is ok...sadly, I'm thinking the ECU may have gone all French on me...auto electrics are some form of dark magic that I do not understand.
    was just about to upgrade turbo and remap ECU, now I have to spend money just to keep it going as opposed to it going faster...hate that!

    OK unplug each fuse in turn overnight.

    Do you have anything non oem electrical fitted to the car?

    no, all standard electrical wise...I did a quick unplug while using some meters, but was getting all sorts of readings...was still drawing around 15 amps, then drop to 5 then zero, then back up...seems to be either the central locking or traction control...I know the 207 is renowned for having issues with the traction control...can an ECU be reset or can the traction control be permanently turned off, etc?
    So, should I start on the engine bay fuse box or the interior fuse box?

    Start with the maxi fuses.
