Finally received the new head sensors and set aside a day to fit and fiddle but no luck, still got the head turning rapidly one way and red light, this is starting to get very annoying. Have checked all connections yet again and checked batteries again, all is good there just won't work properly Any idea's Arpurchase?  Built so far R2D2 building Samba T1 and loads of lego

Head turning rapidly may be the head motor (which has a speed controller built in) but I think this issue also causes a problem with the MCU - so might be best to replace both at the same time.

Request both & replace both at the same time is best Also as a side note, do check that connections are the right way round on the motor & boards - some people found this also causes the same sort of issue.
