Hello, newbie here. Thanks for the add. I purchased a used Coolster150cc atv to tinker with. I have replaced the stock CDI, which was working fine, with a so called performance adjustable CDI box. It starts a runs fine but won't shut off with kill switch or key switch. The box is orange in color, 6 pin, clear epoxy circuit board and small timing adjustment screw. No manufacturer name. I've reinstalled the original CDI and it's working as it should. Any suggestions on how to get this box to work would be greatly appreciated. Thank you.

 

Disregard above post. I assumed i had a dc system because I had lights when the atv wasn't running. I have the wrong cdi box. After testing i have an ac system. My bad for not checking.
