the reason i could tell it was the battery that was going open circuit was i have a second head unit wired directly onto the battery and it was also dead.
in my case it was a few knocks to the starter as well to get it to stop shorting out as i was trying to start the car that also helped.

if all else fails, brute stupidity and a large heavy metal object always wins in the end.

TO follow up this thread - I have been driving around since I wrote it with no great inconvenience - the most difficult thing really has been getting used to starting the car more slowly and waiting for the electronic whurring of what I think is the petrol pump to stop before I start the engine.

If I do forget this and turn the key all the way without this pause occasionally the elecronics die. I have discovered the best and quickest way to remedy this is to disconnect/reconnect the battery positive - breaking the circuit for only a few seconds seems to restore the car electrical system to normal.

I remembered the batt. positive terminal connector has probably always been a bit loose since I gave someone a jump start so I've made a point of tightening it in case a poor contact is making it overload.

Indeed, could giving the jump start have buggered my battery slightly? I hope not, I will never be so kind again

Oh.... and what IS the whurring sound I hear when I first turn the key?

Thanks for everything.
