I took the machine back last week. Finally got a call yesterday that it was ready. He reconnected the internal cables so at least it has power. The embroidery unit works fine. I just can't do anything that requires the feed dogs.
This repair person has been working on Viking machines at least 8 years. They are the nearest Viking Dealer. I won't go back.
After the first of the year I will take it to another shop that offers free estimates and see what they have to say. In the meantime I can at least do embroidery. I will probably end up selling it for parts and use the money for a Brother PE770 if I want to continue to embroidery.
