MOPED ARMY

_I am now seeing about 10 – 12 out of the gray wire that goes to the spark plug coil but there si no spark because there is not enough power_

Have you removed & inspected the spark plug wire, and cap? The wire should have shiny metal visible on both ends, and the cap should read between 1-5Kohms. The cap threads into the end of the wire, so unscrew it to remove it.

I'm not sure what you mean by 'not enough power'. Can you better explain that? Do you get any lights when you are trying to start it?

You should have more like 10-12,000 volts.. which will destroy most any meter, so don't try measuring it. Also, the voltage is a quick transient, and won't register right anyway.

Like I mention, check the quality of the plug cable connections, and the resistance of the cap. If you find an issue, fix it.

If the bike still isn't getting spark (use a new plug) then I'd suggest you clean the points (they should read under 0.2ohms when closed) and re-try. If there is a spare condenser on hand, try it.

If you had voltage before, then you must have disturbed a bad connection when you were inspecting the parts.. check the adjacent connectors for a bad connection.

It might be the source of all the trouble.. that would be good luck.

They are simple systems, and the coils themselves usually don't go bad. Problems are usually due to bad connections, broken wires, etc.

Of course, points and condensers have the same issues on these bikes as any others.
