I have a 1972 Mercury 200. Some history on this engine is it ran fine until it was involved in an auto accident. A drunk driver hit the boat it was attached to. The outboard itself was not struck but the impact damaged the transom clamp and shift linkage. I basically took the engine off and put it on another unit that didn't run as well, however now I have no spark.

It is manual start and runs off a magneto system. There are two green leads coming out going to the 2 ignition coils. Then there is a brown lead coming from one stator and a white coming from the other. If I hook up the longer green lead and the white to either ignition coil I get spark from that coil, however if I hook up the other two leads to either coil I get no spark. I also get no spark from either coil if they are all hooked up. My assumption is that the system is dupping voltage somewhere else (shorting) when I hook up the brown and corresponding green lead. So I am getting ready to pull the flywheel.

Am I on the right track?? Any suggestions or comments would be greatly appreciated. Any other tests I should run???

Thank You
