Hi! For the first time in my life I connected the battery on a Porsche 944 S2 the wrong way round! Now the car won't start. I've checked the circuit diagram and there is no spark. Anyone KNOW EXACTLY what I will have damaged by doing this stupid thing! I'm breaking up the car and have sold the engine - hence the reason why I want to start the engine before I remove it. Many thanks - Michael. P.S. It's a U.K. car.
