Thanks. Being a software guy I made a last ditch effort at moving a few pigtail connections around in ways I wouldn't think would make any difference rebooted, and now I have voltage and heat. Machine Leaning works the same way. I had the board back in before connecting the pigtails and never checked that the tabs were all connected. Below is what worked and is still working 15 hours later.

I'm not sure where to look so see if the relays are closed or am just too blind, but I read 120v on both high limit relay tabs when power is on, 120v and 0v on the heater relay tabs when the power is on but heater is off in startup, and 120v on both heater relay tabs when the heater light is on. I did notice the light goes off and the multimeter goes to 0 when I turn on the high speed jets to pump 1 or the jets on pump 2, which I had never noticed. Any chance this is a bad heater element?

Everything works and I have no error codes. My heater light comes on and I can read 120v from the heater relay tab and ground. I didn't know you could see the relays open so will go take a look. Can you hotwire the relay to test it?

In case anyone finds this thread the part did not fit, either on the power posts or the screws. This looks like it would if you desoldered the posts https://hottubpartsofamerica.com/copy-of-relay-zettler-t-90-type-spst-15vdc-coil/ but I never found it and just made pigtails as described in the post above. I have working pumps and no errors now, but no voltage to my heater.

Thanks!

I have a Balboa 2000 LE controller with a 52320 circuit that suffered a terminal block failure. https://photos.app.goo.gl/j3MgQsKx99pRfJSy8 The board was working but tripping a breaker and visibly arcing, and the block fell apart when I unscrewed the connectors. https://photos.app.goo.gl/Vq7NwoYDANVFMeYL6 The part does not seem to be available, so I was looking for advice on repairing it. A 5 circuit version is available, though I don't know if I could cut the connectors off and have the screws line up. https://spacare.com/5position50ampterminalstrip.aspx Also,
