I have a 1989 Johnson 225. I had to recently replace the stator. Engine quit running and had the insulation coil meltdown. I now have spark but I have to disconnect the blk/yell wire from the shift interrupt switch or with blk/yell wire connected the motor will run with main harness,red plug, disconnected. The shift interrupt does test o.k. I replaced the key switch thinking it was the problem, not so. thanks in advance for any suggestions. Not sure if this is related but I do not have current at my choke primer now. Current is at choke terminal at ignition switch.
