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.
