EDIT: never mind, sounds like you’re back up and running. If problem comes back, post here and we can compare CDI temps if convenient.


Actually that thyristor should be fine, i would hold off sourcing the 120, tho higher voltage spec won’t hurt.

You mention your CDI runs quite hot, mine warms up but not hot exactly. Wondering if something in the CDI is overheating.

Do you by chance have an infrared thermometer you could check temp after running for a few minutes? I could do the same as a sort of controlled experiment and compare temps. Sounds like the cutout happens pretty consistently after 20-30 min… is something overheating.

Also, Pete has a good point about the green wire, the copper strands can fatigue and break internally, so it’s worth checking or perhaps replacing just to be sure. But that is less likely to happen with regular timing.
