Evinrude 9.9 HP Outboard Ignition
I have a 1996 Evinrude 9.9 HP 2 cycle, 2 cylinder outboard which has a weak or no spark at the spark plugs.
From what I can see on the engine and some parts lists it appears it has a "coil" in addition to the magneto spark energy from the flywheel (assumption, I have not pulled the rope-starter/cowling). I think this is what is in the rectangular housing that has the two high voltage spark plug wires coming out of it. The other wires are typical looking 18 gauge or smaller wire... and I assume this bring the relatively low voltage magneto current to the coil where the voltage is stepped up to spark levels. This may be the faulty unit. But, I'd like to have some idea of what the coil is... i.e., can I read a low resistance path from the spark plug wire back to ground? That is "see" that the coil is not open. It would be nice to have some description on how this ignition works... I have searched the web.
