Right,was driving my car today and the big think amp lead was connected to the battery but not the amp.Therefore had a live wire in the car.This then earthed and the car cutout ,no ignition.Phoned R.A.C and he came out disconnected the lead from the battery,but it still wouldn,t start.He said it has fucked up my E.C.U....I thought he was talking bollox,but it still won,t start
