Hi I am new to boating so try to get a merc 120 running but dont seem to have spark coming to the distributor. I have check every thing I can think of new coil points rotor distributor cap. have 12 volts positive to key side. and if I open points have 12 volts to negative side. but no spark . I know the coils is good. I test the ohms on the coil wire it 14 inches 7mm autolite silcone suppression cable. it measured at 200K setting 4.1-4.0. this seems high to me but I cant find any specs. I also dont know have continuity at least the buzzer doesn't sound when I set on that. help I never had a cable that didn't have continuity before or is it because the ohms setting .
