Thankyou roadster, that's a very helpful article you linked and I now have an insight into how the electrical system works, although I'm far from having a complete understanding.
Here's what I don't understand. If the depletion of the 12V battery is responsible for certain functions resetting or switching themselves off, why isn't it consistent ? e.g. not all of the usual suspects are turned off or reset each time, it could be one or three different functions that are affected. Why is there no consistency ?
Another thing I don't understand. Whilst I think I can understand that short runs in the car with little braking and coasting will not put much charge into the 12V battery (is that correct?), I took the car to France for a month in May where I did decent runs most of the time in very undulating countryside and still I was getting functions resetting or switching off.
I did check for insects and closed windows yesterday and nothing untoward was found. However and perhaps unreasonably, I still suspect it had to do with battery drainage, but that flies in the face of a drained 12V battery shutting systems down, as how would the alarm continue to operate. Maybe my alarm going off is a separate issue, but coincidence suggests it isn't.
I found out yesterday that I do have a terminal in the fuse box enclosure, but I have no idea how to use it to jump start, trickle charge (If that's even possible or allowed) or take a voltage reading from it. I do have a little voltmeter that plugs into the cigar lighter socket, would that tell me anything useful ?
Most of the above are just my thoughts and for others to read and mull over, I don't expect you to have all the answers, but by throwing everything into the mix, maybe an answer or fix will emerge.
Addenda; Might have been previous about the alarm. Just been out to open the car and reset the interior alarm. Whilst in the vehicle I discovered an elusive, annoying little fly which has now been dispatched to fly heaven. Relocked car and spent quite a long time afterwards talking to my neighbour and thus far the alarm hasn't gone off. Hopefully, end of story>
