There is no response when I move the Wii Remote (with Wii MotionPlus connected).
* Is the connector plug of the Wii MotionPlus fully and correctly inserted?
Fully insert the connector plug into the Wii Remote's external extension connector, and slide the LOCK switch in the direction of the arrow until it locks.
* Are the batteries correctly inserted into the Wii Remote?
Insert the batteries correctly into the Wii Remote.
* Are the Wii Remote batteries running low on power?
Press the HOME Button to check the power level of the Wii Remote batteries, and replace them if necessary.
* Is the Wii Remote that you are using synchronised with the Wii console?
Synchronise the Wii Remote that you are using with the Wii console.
If, after checking the points above, there is still no response to your movements, disconnect and reinsert the connector plug of the Wii MotionPlus several times, check that it is correctly inserted, and try again.
