I have a 1975 mercury 850 with the thunderbolt ignition system. I went to start the engine yesterday and it would not start. I checked the spark and thier was none. I checked the red and white wires and only the red has power. I checked the rectifier, coil and they are fine. I did the test with jumping the brown and white and i got nothing, i even jumped the white and red wire. What should i do next? Please help me it seems like your really know what your talking about.
