anthropic, short the 2 motors one at a time to the battery. If they spin, then it's the controller.
Just curious, but how many feeders do you have on your pond? 8 feeders seems like a lot.
Al, I've had two feeders short out due to flooding. One feeder went bad after lid came off during thunderstorm, drenching feed & motor. And now my latest feeder purchase has stopped for unknown reasons.
I was able to get one of my flooded feeders working again, but only for a couple of weeks.
PS Thanks for suggestion re controller. I'll try replacing it.
