Hello. My name is Tan.

The auto bilge float switch is shorted or stuck in the up position. To fix the issue remove debris from under the float switch or replace the switch. This switch could be separate from the pump or be part of the pump depending on what was installed.

You can disconnect the auto float switch if the switch is separate from the pump. Disconnect at the battery directly. There is a wire with a fuse that is connected directly to the battery. The boat is wired this way so the pump will still work on auto with battery switch off.

Locate the brown wire with fuse at battery to disable pump.
