A couple of days ago I had an unexpected flat battery. I got the battery tested and they said it was fine, just needing a re-charge. I re-charged it for 12 hours so it was fully charged and put it back in my car. All systems are now go apart from the battery light on the dash that doesn't come on at Position II. The starter motor turns fine but the engine won't start.
It says in the user manual what is wrong if the light fails to go out but not what is wrong when the light never comes on at all.
Any help would be much appreciated. Thanks
