2006 SV211 TE - rear ballast factory pump help

[blakehales06@gmail.com]

I removed both rear hard tanks (the marina actually removed them) and plumbed in bags.

Starboard side - I was able to locate the factory cable/connection, so I removed the sensor from the factory hard tank and taped it on half full and connected it. the factory pump allows me to fill and drain and works well.

Port side - I cannot locate the electrical cable/connection (I have spent hours searching, it disappeared like it never existed) The factory pump fills perfectly but it will not drain. The light flashes on the port ballast button signalling it's draining but nothing happens.

Any ideas? How do I drain the sac using the factory pump?

Check the relays for the pump in the port rear storage. Mine has two relays to switch the polarity to run the pump both directions.

Thank you for the info ROCKer. I'll check that out next weekend when I get back to the boat.

Take your voltmeter and you should be able to track it down pretty quick. DM me if you want to discuss. I don’t have the exact configuration, but do have a little knowledge of the pumps.

So, I have a 2006 SV211 Team Edition, and my pumps work when filling, but do not come on when trying to empty. The original owner took the hard tanks out and replaced them with Big Bag ballast bags. I have to manually use an external pump which is not something I want to get use to. I'd like to use my buttons on the dash to pump the water out of the bags. Someone told me that I should rewire at the switch (at the helm) to see if the pumps go in reverse, but I do not know where that is. Would someone be able to help point me in the right direction?
