Kevin,

I need to change out the pump on my shower sump. I will need your help to rewire it.

The pump has two wires. What is the best way to stop the power to the pump? I do not see any breakers,fuses etc.

Thank you for any help.

Dan

Hi Dan,

If you cannot find the breaker, go back to boat wiring basics and disconnect the battery.

Thank you for your reply and patience.

This is my first cruiser. I have two “house” batteries and one for the motors. If I disconnect their grounds will I screw up any of the marine electrical system when I reconnect and need to reset any systems? (i.e.. motors,generator,computers,gps etc)

Hi Dan,

The pump runs on 12 volt DC and there is no real danger if you short out the wires.

Make the connection one wire at a time. The worst thing that will happen is you find out where the shower sump circuit protection is.
