Hello

I recently posted a thread concerning my sound system in my Brava. The stereo would turn itself on and off whilst the car was no in use, therefore draining the battery.
The main suggestion was to replace the head unit with a new stereo, as this seems to have cured most people's problems. I have gone for weeks without central locking as I've been saving my hard earned pennies for a new stereo, surround, and fitting. So yesterday I handed my pennies over and bought myself a shiny new stereo (I even treated myself to some new wheel trims!). Imagine my dismay this morning as I went to my car and the central locking wasn't working! I thought this might just be the fuse. No such luck, the battery was dead again!!!
After a little temper tantrum, I have come to the conclusion that all cars hate me!! (My last car was a Peugeot 309 that kept trying to kill me with brake failure!!).
If anyone can tell me where I've gone wrong I would be most aprreciative!!

Thanks in advance.

I have left my stereo on loads of times overnight without any problems (except my memory ) I would first start by checking your battery then investigate your locking problem as it sounds like a solenoid is faulty.

there were a few cases lately where the standard stereos were remaining on even when the ignition was switched off, and owners were unable to switch them off.

if you replaced your stereo with a different one, and that one is not staying on, then the stereo isnt the problem. get the battery checked, and check for drain with ignition off.

the central locking is probably not related, although a short to earth in the central locking could be the problem as the central locking is wired direct to live, so it can drain the battery with ignition off. when testing for drain, try removing the central locking fuse to see if the drain stops, if it does you know the problem is in the central locking circuit.
