I have a 1986 9.9 Mariner. I have lost ignition to one cylinder. It seems that when it is cold, it fires, when it gets warm out or I run it and it warms up, the cylinder stops firing. I have read here how to switch the ignition leads on the coil and wherever the good lead is, it will fire, so I am assuming that the coils are OK. Here is my problem. My repair manual says to test the various components with an Ohms tester, but mine doesnt have the scales they want, 1 , 100, 1000. Mine has 20, 200 etc. HELP
