Had my boat out last night and was trying to get the livewells filled up, but whatever I tried I couldn't get it to happen. First, this is what I have:

Aeration switch: up is manual, middle is off, down is auto
Livewell control valve: pull to open, push to close
Timer: off - percent run time - fill

Next, my understanding of how to fill the wells. Push the livewell control valve to close. Turn timer to fill. Flip aeration switch to manual and fill wells to desired level. Once it is full, I can either turn aeration off or use the timer to set how often it aerates. This is the process I used last night, but when I flipped the switch to fill the wells I got no water coming in. The only way I was able to get any amount of water into the wells was to open the valve. This let in enough water to fill about 1/4 of the way full. I tested the control valve when I loaded onto the trailer and it will hold water in the closed position, then drain water out when opened. I can also hear the pumps running in both manual and automatic. So the only thing I can figure is I have a bad pump or something is clogged? Or is it some kind of rookie mistake on my part and I'm missing something obvious?
