Thanks for the explanation. I have a peak meter & get about 160 peak volts from a typical good or new cdi source coil with say 350 ohms resistance on a full flywheel mag. So what would i expect from a points mag source if i peak voltage tested with it not connected to points or condenser--just coil only. Man when i was young i never had much luck deciding if a points coil was good or bad & had a Honda 50 which ohms tested close to spec but probably only talking a couple of ohms or less. But a new source fixed it even though i didn't believe it was faulty. Points source coils lasted well & 'that one' is the only one remember from back then. Later with cdi source coils with fine windings gave us a new lot of constant headaches--when ya not understanding properly . We had an old guy locally who rewound coils for a living which was very handy. Talking the "80's by memory. Nowdays just go on ebay etc & find one. Wish i fully understood it all but i'm too old to learn now haha.

You should expect a similar peak voltage with a points coil. The difference would be the amount of current each can produce without overheating. The points coil with heavier gauge wire can produce more current without overheating. The typical failure of either of these is thru the wire insulation which is even thinner on a fine wire CDI coil.

Now I'm really stumped. I just replaced the points and the condenser and still nothing.

The manual calls for a 0.6 primary resistance on the ignition coil, and I'm getting 1.2.

The secondary should be 6,000 and I'm getting 6,500.

I'm using an aftermarket universal emgo coil. Could the extra resistance in the coil be affecting it? It's weird how it ran fine but then just stopped, that's why I didn't think it would be the ignition coil.

Have you tried another spark plug and another plug cap you never know? I hate electrical problems 

I threw another plug in, I think it sparked randomly a couple of times, then nothing. 

I haven't tried another cap yet, but I'm just running a straight cap ("dyna" brand wire and cap) without a resistor in it or anything. 

If you have a reversing drill that will turn it, just sit back & spin it & watch in a low light area. Works for me & saves all the kick kick effort or asking wife to turn the rear wheel FASTER Dear. Plug out & on earth somewhere of course.

I put a drill on the magneto and spun it. Slowly, it didn't produce anything, but at high speed it produced spark, but weak looking and inconsistent. I put a new plug in and there was no change.

Ok, to my way of thinking it shows a weak source coil. No great arcing of the points "in the dark" looking in while spinning?. If there 'is' then i'd be thinking condenser problems. Sounds source to me. I better not confuse things at the mo but have used a lighting coil wire [lowest output] to prove a point, but need to unhook the ignition source for that trick. After all 'that' i hope i'm wrong & there's an easy answer for you as generally speaking points mags never fail.

Sorry, i see new points & condenser [i'm sure i read it before in hindsight]. So you have a reasonable gap opening & shutting & all that stuff.

Try your original coil with your drill as RT325 suggested
