Lights went out all at once

[walleyealx]

Hello all!

I bought at home that at the pictured setup. After about a month, I was kinda having some trouble controlling the lights with the app and one light seemed to be dimming a bit. You could hear the control unit clicking, but the lights were sorta doing their own thing. Shortly thereafter all of the lights went out (one in the spa, three in the pool). Had my pool guys come out and they gave me the attached quote. Does what they're saying seem to make sense? (It doesn't to me based on what I've seen online) From my research, something like a GFI or breaker would make sense when they all fail like that, but I can't find a GFI nearby and no breakers are tripped.

I guess our next (and cheapest) step would be to replace the transformer. The setup is a bit old and I have no idea about pools, but I'm mechanically inclined and I'm often able to fix stuff like this.

Thanks ahead of time. Any input would be appreciated.

... also, I realize there is a second cable for the salt cell. They quoted me like $1800 to fix it and I happily did it myself a couple weeks ago. Just need to clean up the install.

Use your multimeter and check for 120V into the transformer and 12-14V on the transformer output.

If you don’t have 120V at the transformer then you can look upstream for why you don’t have voltage.
