Hi Everyone, I'm new to this forum. I tried a search but didn't find my problem. My pool has 2 SAm color changing lights (on the same circuit) and BOTH have stopped working, lights don't come on, nothing. I checked the circuit breaker and it is fine; I also checked the outside receptacle that is on the same circuit and it has power to it. I replaced the switch to the lights, thinking that perhaps a broken switch would be the problem but still no lights. Any ideas on what to check next? Reluctant to call my pool supplier as their rates to walk in the door are a little high...... Thanks for any assistance!
