Stator or CDI??

[Cox76y]

Hi all,
Just hoping someone can assist with an electrical issue I have. I have an 2018 ec300. Currently the bike seems to be running OK however, battery is not charging and the lights are not working. I think I may have an cdi issue from a previous mistake I made when I hooked up the battery incorrectly. I hooked positive n negative up incorrectly in the dark. I blew the rectifier./regulator and replaced that. I've checked resistance on every pin in the cdi and have an open circuit on 2 pins. Does anyone know if this is normal? Would it indicate a faulty ecu? Thanks

It's not the CDI as it has nothing to do with running the lights or charging the battery. Look at the factory wiring diagram and figure out if that open circuit belongs there or not. Is there fuse or fusible wire that you popped when hooking the battery up backwards?
