Aqualink no panel lights

Hi,

Converting an old Compool LX-10 panel to Aqualink via the "conversion" kit Jandy sells for Compool...

I reused the transformer from the old system, which was working fine previously, and wiring everything up seemed fairly straight forward. I have no controllers attached other than the iAquaLink wifi. Everything seems to work fine... except... none of the led lights on the panel light up, at any time. The buttons all appear to work, but really hard to use with no led's lit :). Controlling with the phone app via iAquaLink seems to work normally. Measuring the voltage to the board (that comes out of the little adapter board the old transformer attached to), the two outside legs, gives me 27 volts, and if I measure each side against the middle, I get 12 and 15 volts. Fuse on the board tests ok. Chip on cpu 2board is labeled, RS 8 P & S Rev T.2g, and there's a 2022 copyright date on it., and a large "C" sticker by the board number. Conversion kit was purchased new last week, but, of course, don't know how long it's been sitting around.

I tried plugging the board in with nothing attached to it (other than the power), and everything is still dark - no lights what so ever.

I'm tempted to put a new transformer in, figuring replacing the old one (10-15 years old?), is gonna have to be replaced anyway at some point, but my gut is telling me that's probably a shot in the dark.

Any ideas?
 
Welcome to TFP.

I doubt it is the transformer but you never know.

Transformer voltage should be 24 - 28 volts between the two outer wire. Middle wire is a ground and voltage there does not matter.


Where did your get that Aqualink board from?

Aqualink board came from a pool supply place. It looked well packaged and didn't seem like it was a return or refurb. Unless the new transformer resolves it, I'm going to have my pool guy take a look and see if he thinks the board is bad.
 
Problem resolved! Unbolted the board from the plastic frame/buttons to inspect it - didn't see anything unusual, but decided I would reseat the "processor daughter board" while I had it stripped down. Reassembled everything and... wa la... I got led lights!
