so finished work today, got in my car and it started, drove through the gates and the STOP and Battery light started flickering all the way on the motorway. I thought nothing of it. pulled over checked forum on my iphone, nothing. then went to nandos, the ABS, TC, STOP, AIR BAG, BATTERY, Handbrake light staid on...then after a while it wont start. my friend came to jump start me then it started, soon enough i lost all electric so no lights, no windows nothin and managed to get it back home. It wont start at all now. MY friend reckons it's the earth cable. Please help
