Cheers, I may try Facebook. Forgot to mention that is a new main dealer fitted battery (about 8 months ago) I don't have a multi meter unfortunately and I know literally nothing about cars! I assume the battery in the back is the only one and if I wanted to jump start I would use the battery in the boot? Thanks, Rob

Hello, I was wondering if anyone could help please. I have a LS600HL and the battery went completely dead. I charged it up this weekend and the charger says it is fully charged. Upon reconnecting the horn alarm went off, but I managed to stop it. I got into the car with manual key entry. The dashboard was going crazy. The interior lights are coming on and off. There were a few minutes of very weird activity. The situation now is: the battery in the boot is clicking on and off. I can't start the car. The horn is not sounding, but there is a groan/ creaking coming from under the bonnet, at a similar internal to the horn alarm. The main issue seems to be the battery not providing stable power, but clicking on and off every second. I've disconnected and all is now quiet. Does any one have any ideas please? Thanks, Rob
