I am wiring up a mercury 20, 1979 model on my duck boat. I have put two different switches and ended up with the same problem. I can't get the kill to work. I had tired to put a late model sealed switch on and everything worked except it wouldn't cut off! I bought the correct switch yesterday thinking it would work better, but same thing! It wont shut off! I have the stator wire on the m circuit along with the ground from battery. So I touched the stator ( salmon) wire to the ignition wire and it shut off, BUT NOW IT WONT START AGAIN! What have I done? It happened late last night and I didn't have time to try anything else, but What could I have damaged, and why wont the thing turn off? Please help!
