Mechanics Note on distinguishing AC fired or DC fired CDI box :
Wire and Plug
In the GY6 6-plug set-up, you have AC if you have 3-wires going into the 4-plug side and you have 2-wires going into the 2-plug side. On the other hand, you have DC if you have the larger CDI box, 3 or 4 wires going into the 4-plug side and only 1 wire going into the 2-plug side.
AC And DC Size
In general, the DC CDI’s tend to be larger in size than the AC ones.
Headlights
if the headlights turn on without the engine running, (with just the key on), it is a DC system. In the AC system the headlight requires the engine to be running. Another indication is, if the engine will only run with a battery it is DC. If it will run without a battery, it is a AC system.
