I bought a boat a last summer and since then the 3 ballast puppies stopped working. I found out that there was a wiring problem. I then rewired the pumps and am sure that they are getting the correct amount of power. When I turn on the pumps (the boat is not in the water yet), I do not hear anything out of the pumps. However, I do notice that when I turn the pumps on the voltage off of the batteries drops about 1 volt for about 30 seconds and then goes back to normal.
Is this normal? Should the pumps not make any noise whatsoever due to the run-dry system? Or is something faulty with the pumps?
Thanks, Eric
