Got another issue I tested my batter charger last night and there was a green light and I've plugged the battery in the lights gone red and it started too charge I unplugged the battery and turned off the main plug but left the charger in the wall I've woken up too stick it on charge and I've turned everything on but no light comes on the charger I don't know what's happened but I'm assumed the chargers blown for some reason any ideas? (The charger is on and plugged in in the photo)

Most chargers (well the ones I own anyway!) have a fuse protecting the output. Firstly if you have one (essential with a pedelec) use a multi-meter to check for output voltage from the charger. If no voltage start looking for a blown fuse!
