had the main switching unit removed for repairs.
There was a transformer connected to it that I think was an upgrade.
when it was returned, the transformer was removed and the guy that worked on it doesn't remember witch screw terminals it was hooked to.
the transformer sits in the space where a second switching unit would sit.
because it is an economy model, it only has one unit.
If you have this machine with this transformer added, could you look in the back of the controller and tell me witch terminals the transformer is hooked to ?
First: Beat the guy who took it apart without labeling.
Second: Pictures are often helpful in resolving problems such as yours.
