Had to deal with a few other projects, but back at this one.

I’ve pulled the flywheel, it has one newer German coil. Meter reads out 1.5/6.5k and is the top cylinder coil which has no problems.The other coil has an outlined M on it, looks older, fabric sheathed wires, no obvious cracks. It tests out 1.5 on primary and secondary 9/10 times doesn’t register but I can scratch on the wire pin and very inconsistently get a read out of 3.5k.

I did buy 2 new coils (cdi brand 183-4477) and used 1 to replace the bad coil and the new coil doesn’t spark. Both New cdi coils read out with 1.5/8.3k with multimeter so it seems it should work? I swapped the top/bottom coils and the German coil which was on top now successfully fires the bottom plug. I bought 2 just in case 1 was bad so I’ll try the other new cdi coil tomorrow. Skeptical thou? The laminations are definitely shorter, the leg going thru the windings is smaller. Seems like others have success with this model coil thou? Am I missing something?
