Getting harder to find these in AC? We got'em! 5 pin AC CDI for 50-90cc engines. Check pics for plug configurations
.. .. PLEASE NOTE:
If you're not sure if you have an AC or a DC, A "Quick Check" is, If you can turn your lights on with just the key in the "on" position but the engine not running, yours is probably a DC unit but this method is not always accurate because your lights may be run directly from your battery and not your CDI.
A better method is, If you only have 1 wire going into the small "2 pronged plug" on your stock cdi, you probably have a DC CDI. Having 2 wires going into the small plug on your CDI, usually means it's an AC.
The sure fire method is: Count the wires coming from your stator. If you have 5 wires, you have an AC system. If you only have 4 wires, missing the red/black wire, you have a DC system.
You are ultimately responsible for ordering the correct CDI for your needs.
Be sure to check your users manual and/or, manually check your plug configuration before ordering. Because of the nature electronics, we can not accept returns on any electrical items. PLEASE, you need to be sure BEFORE YOU ORDER. Once we ship it to you, it's yours.
