I've had this problem recently after my wheel stopped working completely. I followed this guide to fix it http://www.macnetwork.co.uk/logitech/EnglishVersion.html I changed the Mosfets like the guide said and I cleaned the motors so both are 30 Ohms. Today I plugged it in and powered it up and it starts to calibrate at normal speed, it goes fully to the right and then back to the left but stays at the left. Then it goes to the right again and then back to the left but does not return to the center. Can anyone help me here? Thanks!
