I also checked all the wires on the thyristor. I also checked the yellow wire with the ohmz reading while pumping it never dropped from infinity which I think means it never produces any current, is this correct? If that is correct then I would think the culprit is the pickup aka the yellow wire? I am guessing if the yellow is the pickup it would read something, but since it would read 0.2v according to the manual I think my meter just doesn't read it.

All reading taken on the 50v AC setting with an analog multimeter with a needle so very hard to get accurate readings while pumping a moped. The green wire came up with around 30v, the blue came up with around 35v, the red came up with around 45, the white nothing, the yellow nothing. I also checked the other wires from the alternator. The problem seems to be the thyristor but I am unsure as I have never worked on a 2 stroke before, and never worked on anything made before 2012 before today. I can tell the issue is no spark because when I read the end of the spark plug boot I get 0v!!! I trace down the line and find the power reaches the thyristor and then does not go to the ignition coil.

Everything is all cleaned out, everything hooked up properly. and how 3 cans of carb cleaner is what it takes. well let's just say I now know what 20 year old solid gas looks like. I got this moped for free and all the wires were disconnected and the carb was. So I have been trying to figure this out all day now. I work on scooters a lot but this is my first actual moped.
