I have a 1989 75 hp Mariner 3 cylander which does not spark on any cylander. I have receintly replaced the switchbox. I checked all plugs for spark. Does anyone have any idea what could be the cause?
Pull off the flywheel and inspect the magnets and stator coils, take a wire wheel to the flywheel magnets to clean them up, and emery cloth to the stator coils.
Laddies I did a resistance check and I am getting 507 for blue and 505 for red. The magnets on my flywheel look like one solid piece so I am assuming they are bolted in.
I would lean towards a stator but it would be nice to test the system with a DVA to know for sure. If your magnets ars bolted you should be able to see the screws that hold them.
