The Necchi Foot controller did not work. I installed a new, after market, and generic foot controller. (Oxford comma, corrected). It came with my South River parts.
I was sewing along happily but noticed a hum despite no pressure on the controller. It sure sounded like a sewing machine motor hum. I thought, perhaps, it might be the fluorescent (shoot I should have left fluorescent misspelled for someone I know) lights. I turned them off. There are four in the sewing loft.
I still heard the hum.
I leaned way into the Necchi. It most certainly was the motor. Drat. I unplugged it and picked up the foot controller. It was hot. Very hot. Extremely hot. Too hot to handle. Double drat.
I did not want to mess with fixing a foot controller. I wanted to sew. Triple Drat.
I found a Singer button foot controller, removed it's wires and took the "new" controller off of the Necchi. It had cooled by this time.
As soon as I looked at it I understood the problem. The connection was not, well, disconnecting despite my removing my foot COMPLETELY from the controller each time I stopped sewing. The dang thing is crap; poorly made. I was unable to make any correction or adjustment.
The Singer foot controller works well. It is a bit stiff. Maybe I will fix that sometime but not now. I want to sew.
