Bought a 1974 50 HP Evinrude, has 150 lb both cylinders, had a slight spark but not really a good one. Checker inline fuse and it was broke right at the metal end . Calls for a 20 amp but there was not one in town. But I did find a 15 amp, put that in and now not any spark at all. Pulled both coils and ran a olm check, NOTHING on both coils. So what did I do? Did I blow both coils? What else do I need to check? Thanks and Merry Christmas to all
