Hi Micheal.
Thanks for your reply. Yes the motor does still labour without the OTA. When I replaced the motor,before assembling l held the gear with my finger and thumb then ran the motor. Clockwise, I couldn’t stop the motor but anti-clockwise it was quite easy to stop it. Because the original motor did this also ,I thought that maybe this was normal and that I’d replaced it for nothing. (Expensive mistake. But at least I have a spare motor). Anyway when I’ve fitted it ,the problem is still there. Hence this post. I’ll check the gear mesh and try and find any articles on the continued motor operation.. Do you think it might have anything to do with the small circuit board on the Dec motor side of the mount.?
Thanks for the suggestions Micheal..
