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

I almost forgot one detail. Both sets of leads test 360 volts when not connected to the coils. So my assumption is when I hook the one set to the coils I add resistance which is causing it to short somewhere else.

Just an update in case anyone else has the same problem. The brown lead to the ignition coil was shorting on the stator. Replaced the wire and I have now have spark.
