Hi and welcome.

You may find more suggestions that you can imagine if you try the
search key.

Points? cdi?
what year OR model name, engine size would help dagnose your problem.

The color may even offer some clues.

See if the following words light up as a clickable link

service manual

...and please keep us posted.

We all need to know the answer to this problem.

..oh, and Everyone likes pictures.

Generally, as the flywheel spins, the magnets charge a coil or stator
and it puts out ac current.
Almost impossible to detect with a digital meter but possible if you
have someone spin it for you.

Ac current is changed to dc some how depending on the model,
and then the coil can use it to fire the plug if your trigger mechanism
is working, either points or sensor.

Anyway, have fun.
The search key is always a great way to learn more than you'll ever need.

I usually read all the posts on a topic I'm having trouble with.
