Relatively new boat owner here. Purchased first boat in May - a 2007 centurion elite v c4. Now seem to be having issues with the center ballast. I could tell it wasn’t filling so I popped off the floor cover to take a look at it and the pump. When I hit the empty switch the pump will run, but when I hit the fill switch just get one clicking sound that sound like it’s coming from farther back near the engine (I did have the engine running when I hit the fill switch). I pulled the pump out to see the impeller and it was the same when I tried there as well. Impeller spins on empty, dead on fill, just that same short click noise coming from somewhere by the engine. Is there a trick to filling the center ballast, or is there a breaker or fuse or something that could have blown that’s preventing it from filling? Any help is appreciated.
