My SR3 seemed to run out of battery yesterday and decided not to start in the afternoon. The side pod battery showed 12.4v and the engine bay 12.7v
I charged them up this morning and started the car, then measured at 2500rpm when they showed 13.2v and 14.4v respectively.
Does this suggest they are being charged up OK? Or should I be expecting higher voltages?

Try as I might, I couldn't find anything wrong, and as if by magic the problem went away.
It came back again last week, and so I changed the starter motor (I carry a spare since discovering what involuntary reversing does) and problem solved.
Turns out it had an intermitant fault, but I was fooled by it not working one day then OK the next.
