My pool lights were a little finicky the last couple times I tried to turn them on but they did turn on. That is until the other night. There are two color LED Lights with a pentair 300w 12v Transformer. The breakers aren't tripped. There are no burned out parts or evidence of burns or smoke.. The relay still makes switching noise but no lights. It is on AUIX1 This is my first time troubleshooting LED lights on the pool... I have a good multimeter. I have made repairs to the heatpump relays and other parts before.
Since both lights aren't working I suspect something else has gone wrong.
Is there a troubleshooting guide?
Any advice appreciated.
