My engine is down 2 cyls #2 & #5, has good compression-no spark. Carb engine. Moved coils around and miss stayed with 2&5. Had no power on the yellow wire@ cdi module, traced the harness and found a bad splice. Repaired it and ran new wires. Now I have 12v on the yellow wire but still no spark. Checked resistance of the crank sensor-good, connections good. I have been an auto mechanic for almost 30 yrs and this is boat #4 over the last 25 yrs. Please help
