It looks as though after all the sudden loss of power the other week was a sign of problems.
The replacement battery started it running again but after jus a couple of weeks it again stopped in the night without even showing the low battery warning until it restarted about 9am when the sun got to it.
This is a documented symptom of faulty capacitor – not only does it hold less charge but there is some kind of shorting in it which drains the connected battery in days.
Anyway I’ve set the spare Vantage Vue up again for now and after a bit of research found a suitable capacitor from maplins – under £5 delivered.
Although soldering this is in place is on the edge of my ability it will be interesting to do.
I am tempted to snip the old one off (it has quite long ‘legs’) and solder the new one onto the legs rather than risk overheating the board.
I do have a quite suitable iron and solder and flux - which I used last year to do a comparable job on a webcam connector. Still working!
