If it is a DC type CDI, then one of the wires will be powered with 12VDC when you turn on the ignition.

AC types rely on AC power from the stator produced when kicked over.

You can unplug the connector for this test. Very simple with a multimeter on each wire, one at a time, on the wire side (not the CDI) when disconnected. Black wire from the multimeter needs to go to ground (engine, frame, or battery). Red multimeter lead to one wire on the connector (at a time). See if any of them gets 12V when you turn the ignition on. Voltage amount should be the same as what you get on the battery itself (maybe 12.7 VDC, for instance).

It is described in the Templar resource guide in post #9.

Presumably, the input power lead on the incoming wire will get AC voltage when the engine is cranked. I haven't tested this myself, but that's my guess. Dirtbkr188 is good with this. Maybe ask him via a pm
