Attempted battery change DIY style. I checked for written instructions before commencing and I've done this once before, however, I connected the battery the wrong way round and sparks flew.
I connected the battery correctly and the car starts and drives fine. However some electrics have gone now.
Audio, windows, internal lights, central locking.
What have I broken and what do I need to do to fix it?
New battery is a premium Exide with 540 cold crank start.
Any help much appreciated. J.
