Hey John,

The PU wires are fragile, and after 30+ years, they don't handle the constant flexing very well, and IF the repair was just soldering together the old wires, then that's where you should look more closely for additional intermittent breaks. The wires don't split up the line to the TCI, just around the PU coils where they are flexing so much.

As Davinci stated, the solder joints on the TCI where the external prongs are soldered to the PCB can go bad, and resweating/soldering them can correct problems. DO NOT try to take the PCB out of the TCI box, just take the cover off and access the solder joints directly.

PU coils can go bad, but that is also rare.
