Well it quit working Again! (6-12782)
I know it's a POS, But I don't want a static display and I'm not going to shelve it or throw it away. Can't sell a broken item either 
Here is the latest problem, as far as I know, Control box connected to bridge via ribbon cable, and wall wort providing 14vac pwr.
When control box is switched to on, Nothing, (no lights, sound, -bridge or box-) After opening control box, there is voltage through the switch and out the ribbon cable, to the 'Main Board' in the bridge tower.
Now here is a clue, when I disconnect the cable at J4 on the Main board, the green down light will come on at the control box. 
My unprofessional thought is maybe a bad transistor or maybe a bad relay or .......
So, after those pics were taken, I added an in-line fuse at the 'burned' junction, I replaced four transistors (thought maybe...), replaced On/Off switch on control box. Re-installed main board, It worked, sort of, I was able to raise bridge to the midway point, then lower it, then fully raise it, then it Died
Yikes! What a pain!
Anybody out there care to point me in the right direction?
