are there a way to test the trigger on a 76 115hp 1150. I tried the spark test on the switch box that clams was talking about and there was a spark small but it was sparking. I unhooked the trigger wires and checked with a ohm meter. there was continuity with the white and brown but black read .004 ohms. there isn't any fire at all. if the coil was bad then the switch box would'nt spark. every parts house I've tried told me I was out of luck. looked on ebay and found one for a 85hp but it was a4 cyl. I haven't seen clams on the forum for a while. I was hoping that he could help.thanks for any input.
