Andrew88 Posted May 21, 2020 Report Share Posted May 21, 2020 So I put a new harness in the tub for LED lights because mice chewed it all up. I wanted to test the lights without water in the tub so I gave 12v from a car battery to the lights, they lit, and at some point while checking each light, they stopped lighting. Did I just blow EVERY LED, or is there some sort of circuit protection built into the boards in the harnesses??? Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted May 21, 2020 Report Share Posted May 21, 2020 Where did you hook up the battery? Have you tried them using the spa control for power? Quote Link to comment Share on other sites More sharing options...

I disconnected the harness from the board and gave it 12vdc. There's no water in the tub so I didn't want to power the entire panel. Is there any circuit protection in the PCBs that would cause them to go out? Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted May 22, 2020 Report Share Posted May 22, 2020 There may be a fuse in the led controller. I am not sure if the controller is dc or ac, but that could be an issue. I would fill it up and try the main board for power. Quote Link to comment Share on other sites More sharing options...

Yeah I bypassed the board when I tested them, but I'm moving the spa to it's final resting place tomorrow, and then I'll fill it and see if they are toast after the electric is hooked up. Once it's in position, I won't be able to access the side panels anymore, so it is what it is. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted May 22, 2020 Report Share Posted May 22, 2020 I see. If you disconnect your heater you should be fine for a short dry test, if you want to run a wire to it and check before you set it in place. A 12 gauge will do for testing with no heater.

d1dennis2009 Posted May 22, 2020 Report Share Posted May 22, 2020 The LED lighting is likely 12V AC, DC voltage is not good and could have caused damage. 1 Quote Link to comment Share on other sites More sharing options...

Some are AC some are DC...need more info...brand of spa, what control system, stereo? 1 Quote Link to comment Share on other sites More sharing options...

It's a Saratoga Canfield model. Again I powered the led circuit independently of the main board. No stereo. Am I fucked? Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted May 23, 2020 Report Share Posted May 23, 2020 Maybe. The led assembly will often have it's own controller that is in turn controlled by the main board. There could be a fuse in there. Check for it. Most circuit boards have a 12 volt ac supply for the light, and dc voltage applied to an ac circuit can damage it. But yours may have a 12 volt dc source, I do not know for sure. I would need pics of your circuit board to determine manufacturer and model, then have to look up the specs for it. Which will only tell us the voltage, not if your lights are destroyed or not. So, run a piece of wire to your spa and disconnect your heater. Send power to it using the circuit board connections, as you should have to begin with.

Andrew88 Posted May 27, 2020 Author Report Share Posted May 27, 2020 UPDATE: all the lights worked after installing it in its permanent location! Must have been circuit protection shutting them off, and thank God for it! Lesson learned, if you want to test LEDs, use a variable power supply. 1 Quote Link to comment Share on other sites More sharing options...

rodolphemyint7 Posted March 23, 2022 Report Share Posted March 23, 2022 understand; I also burned a lot of LED elements because of such experiments. I used to like to test electronics and create interesting and new devices for myself, so I also learned everything specifically in practice. Lately, I really want to create something like a tape from https://www.vont.com/product/smart-strip-lights-led-strip-lights/ and be sure that it is battery powered; this is my main goal. I will be glad if you share any tips on how to make everything not burn down. Quote Link to comment Share on other sites More sharing options...
