I have a 70 hp Chrysler motor that I recently acquired. the motor turns over great, has good compression, but gets no spark at any of the 3 cylinders. I have power going into the ignition box, but wen it turns over I have no power at the coil from the ignition box. is the ignition box faulty? Or could it be the stator? is there a cheep alternative to the expensive replacement ignition module? mybe a equivalent from a automotive application? Any help would be greatly appreciated...
