Welcome to the forum! The first thing that I would do is to pull that top cover off and see if you have any water damage underneath on the circuit board I see some polarization film UV damages on the top film as well as the rear, but the way its faded leads me to think that you might have some water damage in there possibly, let me know what you find out I will send my contact information if you’d like to look into a repair as well -AKATV

you can test the reg/rec, ohm the stator and pickup coil, ohm the spark plug coil. there is no way to test the c.d.i. other than with a known working c.d.i. . MAKE SURE YOU HAVE A NUETRAL LIGHT ON THE DASH ?~!..IF NO LIGHT ?..NO SPARK  !.

@AKATV I was told to reach out to you here on my screen. Bike is an 07 400at without gps. I get nothing on the screen but it does light up with the headlights are on. 

What is the best way to check for spark on these machines 

Wonder if someone did the washer trick to lock the front end?
