I have a 1980 732i, and have a problem. A few days ago, a coolant hose ruptured, and the car got not quite dangerously close to redlining the temp gauge. After fixing the hose & topping off the coolant, the car ran fine, and did so also later in the day when well cooled off. The next morning, and since then, have not been able to get the car to start, and it seems I am getting no spark. I am getting 12v to the coil, but no high voltage out of it while cranking. The coil measures 7.2 ohms accross the input terminals, and about 10,000 ohms from HV terminal to either input term. Seems like normal readings to me, but I don't know what is specified for this coil. I have not yet traced back any further than the coil input, and not sure how to procede in doing that. Anybody got any clues for me?
