Has anyone else had this happen to them? The small black wire that is behind the tension knob that thread is hooked thru is missing. here is a small piece of wire sticking out but most of it is gone. I am not able to thread the machine correctly. Has anyone ever had this happen to them? I was FMQ meandering, bobbin ran out and when I went to rethread the machine - NO black wire thing-a-ma-gig! I can not believe it broke off but is probably slipped behind the tension knob. Off the the repair shop it went. Of course the FMQ is not done. This machine is a Brothers 1500s so I was really flying on the FMQ!
