Wii remote only flashes when trying to power on wii system. How do I fix?

Answer 1

its normal if it does that, that means that if u have 2 controllers that 1 is gonna be 1st player

Answer 2

Take the battery cover thing off of the remote. Also, open the little camera memory card thingy on the front of the Wii. There is a red button on both. Press them at the same time. This should sync the controllers.
