I am back aboard. (Jerusalem was great!) Couple of things.
First, all of my voltage measurements were referenced to Pin 1 ground.
Second, I noticed that my board does not have the C1 capacitor, just
I retested the voltage on Pin 5 and determined that it is 24V DC. I
measured and confirmed continuity between both Pin 4 and Pin 5 and
the output positive terminal of the rotary switch with Plug 1
disconnected from the board. That is, there is NO AC going to my
control board. Except for the missing C1, my board looks just like
Thanks for your diagnosis of the failed T1 and fried RY1, RY2, RY3
relays. This is what I had surmised. However, we have no chance of
getting replacement parts for months yet.
I have now have components for my "manual control" box and will hook
this up today and make sure everything works.
That is great news about the new Dessalator board that actually does
what it is supposed to do. Do they have a name or part number for it?
Did you get it from Amel or Dessalator?

have not attempted to fix it because I didn't have access to a 220VAC
50 Hz power supply for testing, but now that I know that the boardvoltage
