Thanks for the reply. Yes all lights are on and would be working OK if I could recharge the battery but I can't. What has happened is the battery box shorted out with a bang and will no longer allow the mains power supply to recharge the battery. It is not a battery problem, it is a problem where the mains power plugs into the battery box. It's blown a fuse or shorted out and needs someone to come out and repair/replace. Thanks ... View more
