Thanks for the input folks, given my excellent record of cocking up any practical activity other than cooking and decorating (paint, not wallpaper) and the fact that my time is at such a premium I suspect I'll be taking it around the corner to the mechanics but at least I am not going in a complete ignoramus now.

New toy ?

Do you mean the car? That's not new, it's my wife's old Hyundai i10 which she uses for commuting. Because she is a teacher it is mostly idle during the kids summer holidays. It's not been a problem before, but it's also possible nobody has ever changed its battery which would be 10 years old ... the battery doesn't have a date sticker.

Or do you mean the multimeter? This is again not new, it's just that I've had enough sense not to poke it anywhere > 5 V and a few mA before. It's a Dynatool DO3144, the sort that I suspect is rebranded and sold by many different vendors.

Best wishes,

Tom
