Beyond that, I don't see what > in the world can be the problem...someone have an explanation? The one that gives 6.5V- is that the big connection in the centre of the coil? That one gives out a high voltage (10-20KV??) at a low current when the car is running. The high voltage is needed to ionize the air between the spark plug gap and produce a spark. You can't really test this high voltage with a standard multimeter, so either do the Muir test, or do the timing light test as Jim suggested. The spark that you see in the Muir test is dependent on how good the ground you are holding it near is. Try holding the large wire about 1/4" away from say the oil cooler base, turn the engine by hand until the points are closed, then with a screwdriver or something similar open the points, and you should see a spark jump between the end of the wire and ground. If nothing happens, try moving the wire closer to the ground. If you can't get anything, then the condenser could possibly be shorted to ground although this is a rare occurrence with genuine Bosch parts.
