There was good news, and bad news.
"Sorry George, but the charger's working fine... which means it's the (much more expensive) battery that's needing replaced."

A very windy day. Bit scary on the way through town tonight. After swimming and some shopping, had to walk the last two thirds of the Kessock Bridge, as it was too wild and risky to cycle in the hoolie that was blowing. First time I've had to do that in a couple of years, or more.
