A few warning lights on and it would not start. Checked manual and suggested flat battery. I disconnected the battery and charged it. Upon reconnecting nothing at all is working. No power at all.

Should not have ignored the warning lights . Checked battery voltage after charging ? Check battery terminals and earths . If you get it running and warning lights on , scan it for codes .

I didn't ignore the warning lights, they all came up at once along with it not starting. Upon checking the manual the only suggestion was the battery so I charged it and thereafter there was zilch, Nothing at all alive.

I had not done so before writing this but decided to check the battery with a multimeter and it read 0.3 volts so that was the problem. I had a new battery fitted yesterday and it is fine. Now I just need to get the radio code to get it working again.

Thanks very much for your response.
