Salut,

I have found some time to work on my Future Spa today.
While I was cramping the pins on J3, I recognized that J3-13 (Yellow white) is missing.

As I have a second transformer + rectifier board from another Future Spa, where the cables have been soldered on the board and cut after 5 cm , I was checking there, but pin 13 of J3 is empty as well.

In the documentation of the Future Spa J3-13 is named as Solenoid Bus.

Is this Solenoid Bus not needed on all Ballys or is this an error in the documentation?

Thanks in advance,
Cheers,
