Guys I just hooked up some new sacks on my boat and it is now doing the same thing. My center ballast fuse keeps blowing but when I turn on to fill one of the others it fills the center one it' the weirdest thing so now I have to use my plug in psunamis to fill my sacs and it is a pain in the a$$. Please let me know when you guys get it figured out

I am not an electrician and I have not experienced the same issue so this may be way-off base, but worth a thought. When I added additional sprinkler valves to my system I was surprised to discover that all of the valves shared a common wire and the second wire going to each valve supplied the electrical current to open the valve.

When we pulled back the plastic shielding near the valve's solenoid we found that each set of wires going to each valve had a diode (basically a one-way path for electrical current) crossing from one wire to the other. If this diode becomes inoperative or unattached it could allow electrical current to travel back through the common wire to other valves' solenoid and thus allow them to open. This of course is just a theory.

As for the blown circuit breaker, I added an additional Mayfair 1000 drain pump to the port and starboard enzo sacs. The drain pumps would run for a few minutes and then pop the CB. After removing the four screw that hold the CB panel in place I found that the Port 1 and Starboard 1 CBs were only rated at five amps. Each Mayfair 1000 is rated at 3 amps for a total of 6 amp draw.

I checked the associated wires on my boat and they are 16 guage. According to the electrical source I found a 16 guage wire can handle a total of 13 amps (the total amount of amps a 16 guage wire can handled varied based on which web site and electrician I talked to, but 13 was the most popular answer). So I replaced the 5 amp CB with a 10 amp CB and problem solved.

Agian, I am not an electrician so please do your homework and consult an electrician before proceeding forward. On a side note I did consult Shell and Travis at Fineline, but last word I got from them was that they are still checking into it.

Hope this helps,
