SAN Ballast Pump Re-Wire

[h2ohangtime]

Has anyone re-wired the rear ballast pumps on a Super Air (mine's a 2002) so that they're not coupled together? I find it really annoying that CC did it this way, although I'm sure wakesurfing wasn't even on their radar in 2002. When I get my 750's, I'd like to be able to fill them independently for surfing instead of both at the same time.

Any ideas on how to do this? I'm sure in theory it can't be that difficult, but in practice, well, we all know about CC's wiring prowess.

Do you have the older pumps or the Jabsco reversible pumps? I actually just added switches and disconnected the pad switch. I like having independent control of the ballasts regardless of surfing or wakeboarding. You never know when you have a very full cooler or overweight friend that you need to be able to compensate for. I can send pics of my install if you would like.

SAN Ballast Pump Re-Wire

I ran new wires to each pump, then to a panel I built mounted below the radio. The panel has 4 rocker switches. I mounted a distribution block behind it where all the pumps wires feed to, and ran a new 10 gauge power and ground from it to the battery.

Eric, I still have the stock aerator (Rule?) pumps in there--one for each tank in the rear with its own thru-hull. I don't have any plumbing to the ski locker because it's not a Team Edition. Basically, I'm trying to build my system in a piecemeal manner because of several factors, but mainly for the fact that I don't want to throw $1000 at a ballast system at once. Eventually, I'm going to have the pumps and the stereo run off the aux battery bank instead of the starting battery, which leads me to my next question:

Intrlaz, when you say you have a distribution panel that all the wires run to, are you talking about a circuit breaker panel similar to the main under-dash unit that all the other accessories go to? I figure if I eventually want to have the ballast pumps and stereo/amps run off the aux battery bank, I'll have to use one of those, but I wasn't sure exactly how it worked.

Thanks guys!

The distribution block I used is from BlueSea similar to these

I mounted the distribution block on the back of the pocket below the stereo head unit. This way I can have easy access to change fuses

I have main power wire to the block running to the common post on my perko switch. I also have my stereo running to the common post. The reason I ran everything to the common is so that all components have power on battery 1 or battery 2. I use my main battery for running and keep the switch on Battery 1. My second battery is a deep cycle I use when we are beached for the day or anchored, and all components will work on that battery as well.

If you were going to connect the stereo, pumps, etc. to only a single battery, you would need to have the perko switched to that battery or ALL, and could never use solely the other battery for those purposes.

I never use the boat in the ALL position, mainly because if one battery is completely drained it will steal charge from the other battery. If you look at posts from David at Earmark, he will almost always recommend stereo being wired to the common post. Obviously to be able to use the system in this way, all the batteries negative posts need to be binded. In automobile terms, the negatives all need to be grounded together.
