Here are a few tips: * If the bike has no battery then it’s an AC-CDI * Age of your bike? Old bikes are mostly AC whereas news one are more DC… * Search in your Service Manual Technical Specifications for AC-CDI or DC-CDI mention. * Google your bike with ACCDI and DCCDI key words * The only reliable way is to measure the voltage between GROUND and the POWER source input of the CDI while the engine is running. Ie: On a GY6 CDI measure between GND pin 4 and Power pin 6 If 12 to 15volts DC then it’s a DC-CDI If 50 to 100volts AC then it’s an AC-CDI * While the engine is running, disconnect the battery and the regulator, * The engine stall because it has no more +12v then it’s a DC-CDI * The engine still run because it’s powered by the spinning rotor then it’s an AC-CDI If the bike has a 12v battery, a DC-CDI can replace an AC-CDI but on the contrary an AC-CDI cannot replace a DC-CDI !
