I have a ten-year old Intellitouch i7+3, with the MobileTouch handheld indoor controller. This evening, I noticed the green LED next to "Pool" on the indoor controller was illuminated. My pump is set to run early in the morning, so nothing should have been running. After seeing the LED on the controller, I looked outside and noticed the pump was not actually running. I pressed the button next to the illuminated LED, but it would not turn off. I tried pressing other buttons, but nothing else would turn on (sheer arcs, fill line, etc). I unplugged the controller and plugged it back in. While it was initializing, I went outside to the load panel and discovered all of the lights were off ("Auto") and one of the three small Low Voltage Circuit Breakers was tripped. It was the first one, labeled "Electronics". I reset the breaker and stood by while the load center went through its initialization, but the same breaker kept tripping. I tried several times with the same results.
From looking at the wiring diagram in the manual, I see this low voltage circuit breaker is supposed to be 12V, but I have no idea where to start trying to troubleshoot this problem. What would cause something like this, seemingly out of the blue?
Thanks in advance for ANY help or suggestions.
