Hi,
Have you tried Tess Electric, they are or used to be able to fix anything.?
The company has a membership on
YF as Tessllc.
If you don't have success with the phone answerer ask for Paul Salenieks by name he is the founder and the smartest Electrical Engineer I have ever had the pleasure to meet/work with.
If you need it PM me and I will give you his cell no.
