Ok my pickup did that to me. My battery ground wire was so corroded it wasn't allowing it to ground properly causing all kinds of trouble. This might be it.

 

Well the power goes through the solenoid and to the switches then to the cdi and is suppost to come out of the cdi to the coil but it doesnt.

 

Well are you sure you getting power to the cdi?

 

unplug the stator/magneto from the harness test the green and red for power then test the red and white for power. i believe im having the same problem with mine. the service manual tells you the exact range of ohm's the magneto should read. in the back of the manual starting on page 290 it gives you step by step instructions on what to test and what the ohm range is for the particular part. it helped me out a lot!!

 

I have tested the stator pick up and primary its good and its new. Im getting 12v in to the cdi but nothing out of the orange coil wire

 

get a new CDI if it works yay if not take it back

 

It is new brand new yamaha $300!!
I would like to plug it in to another running bike and see if it works

 

you can find one for like $65.00 on ebay..

 

f1coop, If your new stator has the two pigtail connections (one round with three white wires, and the other square with four wires) disconnect the square one, and on the stator side there should be one solid red wire......get a small paper clip or small enough screw driver and disconnect the red wire from the clip inside the pigtail, fold it over or tape it for now and reconnect the pigtail.......then try starting it up. Hope this works!

 

I tried removing the red wire, It did not work.... Im looking for another cdi that works if anyone has one I can try or purchase let me know.
Thanks!
