I have the above log splitter which all of a sudden has no spark. Pulled the plug and it looked fine but I grabbed a new one. Before installing it I connected the wire and pulled the cord - no spark. OK, no big deal so its time to check the points for the first time. So I pull the shroud. The coil is on the outside of the flywheel. There is no wire going under the flywheel. Wha'huh? No points/condenser? I looked around on the beloved internet and couldn't find anything specific but a general reference to a "Magnetron Magneto." Whatever. I have worked on stuff that had a magneto but they still had points to control the timing. What the heck is this coil on the outside of the flywheel and no points or anything to control ignition timing? And I couldn't find anything for troubleshooting the 'coil'. Of course I can check the plug wire for an open. And I think I can check the secondary (kill wire) likewise. That's on my list for when I get back from town.
But there is zero troubleshooting info like resistance on the primary or secondary on the coil. But all kinds of posts about people who threw parts at a problem which doesn't lend itself to troubleshooting. And all of those had points, condenser, and an ignition cam and they were under the flywheel. So what's this thing of a magneto (on the outside of the flywheel) with no ignition points/condenser?!? Any specs other than an OPEN circuit? Dang, OEM parts are crazy expensive.
Any small engine guys out there who can explain or give some detail?
