Default Re: How to troubleshoot CDI/Magneto when no spark

Thanks for the follow up. Here's the answers:

I had the volt meter set in the 20V range. I was *mistakenly* thinking I was looking for 12V.

Let me adjust the gap when I get home and see. I didn't have a gap spec, but I couldn't get either the old or the new plug to spark. I am also not familiar with a spark tester. Would you suggest the easiest way is to just touch the side of the plug to an exposed part of the frame while cranking?

Can I put my meter on the output side of the CDI and expect to see anything? Do you know the Volt range I might see?

Thanks for the next steps. I hate when I want to troubleshoot but can't think where to go next.
