MOPED ARMY

First of all, what kind of moped do you have? Orange magnet, yellow wire, etc. don't mean too much unless we know what you're driving!

If the magnet is damaging the coils, it sounds like either there is debris inside the magneto, or [gasp!] your crankshaft is bent and the flywheel is no longer rotating truely. Can you hear/feel rubbing whenever you rotate the flywheel by hand?

Has anything happened to your moped lately that might explain this happening? Have you been driving through mountains of iron filings?

Do you expect everyone that reads messages on this forum to cross reference other messages by authors to derive missing context? Regardless, I went back and read your post. I have the missing information now.

1) Testing an ignition coil with an ohmeter is an unreliable way of verifying that it works. Often coils will stop working under very specific conditions (i.e. under heat, vibration, or high voltage) or they become shorted. The only way to test a coil (or condensor) is to plug them into a working, identical, moped and see if it stops working.

2) A cut coil is DEFINITELY a big time problem. You mentioned that you had a spare. Did you replace the broken coil? Did you verify that the other coils are good? Once again, an ohmeter is not the best way of testing coils. If there is no continuity it will tell you that a coil is bad, but if there is continuity/resistance, that does not necessarily mean the coil is good. Replace any damaged/scuffed coils just in case if you can.

3) You mentioned that a screw had worked loose in your previous post. Did you find out where the screw had come from and reconnect whatever the screw was holding in place?

4) It sounds like you're on the right track with suspecting the magneto since it had obvious damage when your moped started acting up.

Sorry I can't be more help, Mike. Hope you get your ride a-runnin' soon.
