    Sorry I don't have any answer but boy do I hate these integrated systems. Love my old tech boat with basic technology. Good luck.

    Check the circuit for your sump pumps. That should be the only circuit that would be connected with master switches off. If the wiring for that circuit is not correct it will set off the alarm so you don't walk away without a sump pump.

    Just a thought along the lines of gdavis67. On our old sailboat, I missed a wire going to the fire extinguisher system. it had become corroded and, more or less, fell behind the battery box. I could not make the damn buzzer stop buzzing, but we were pretty sure the boat was NOT on fire. So I would look very closely at the wiring of the batteries and be wary of the Bilge pump, and Fire systems. Assuming this is a new problem with the new batteries, and not the reason the old batteries were replaced, it is probably a mystery wire that has fallen out of sight or been hooked up incorrectly.
