I took the battery out to operate a 12v pump down in garden beyond the reach of a car. I put the battery back in the correct manner but when I went to turn over the ignition nothing happened (the internal car lights and dashboard ligts were working but the starter motor didn't turn over. Presuming I'd run the battery down I got my neighbour to give me a jump start, but all that happened was all the electrics went totally dead. No dashboard lights, no hazard lights, nothing.
So, what have I done and what fuses, etc, should I be checking?
The Zafira manual and google haven't thrown up much useful stuff yet.
Cheers.
