The 2013 manual shows wiring similar to the older bikes. The AC powered CDI is charged by the single winding on the stator. The lighting coils have nothing to do with ignition operation and can be ignored. Once the engine runs you can check AC voltage for lighting and DC voltage for charging.

Make sure any component you test is completely disconnected or you will get odd readings. The most likely reason for no spark is a ground problem whereby your ignition key/kill switch/wiring is shorting out the igntion system.

Other than that you're back to the CDI or ignition coil and their related connections.
