So, I'm just arriving at my mates house, on the Vigor, when there's a sort of a popping sound, and the bike is completely dead. I was on a hill, so bump started in second on the hill, and reached his house.
Tried to restart bike, and completely dead. I only fitted a new battery a week ago

Anyway, we put the battery on charge for the afternoon, and I went pillion on his bike to the road racing.
Returned to a fully charged battery. Put it in bike, and she started and I rode home. Then wouldn't start again. On closer inspection, I find that one of the connectors from the reg/rec has disconnected, so there's the answer.
My query is, will I have done my new battery any damage?
PS. The old battery was deco scrap, as it was tested, and found to be done.
