bilge pump diagram

[openseas]

Hi all,
I am installing a second bilge pump to my sailboat. It is Rule 1500, it has two wires: Brown and Black.
I am wondering if anyone has a diagram of how the wiring works, since I am planning to do the work myself.
The original switch panel on the boat has an on and off switch for the existing bilge pump ( I leave it on all the time, and it works automatically).
Do I need another dedicated switch to the new bilge pump.
If I want to include an alarm light or buzz when the bilge pump runs in my design, where it will be on the diagram?
Thanks for all your help.

I believe most of the Rule pumps, including the 1500, come in two versions, automatic and manual. The automatic has a built in float switch, the manual doesn't.

So will depend on which one you have.

Short answer, Brown is positive, Black is negative or ground.

You shouldn't just wire the pump directly to the battery so need to go to a switch or circuit breaker on you DC panel or somewhere so yes you need a switch. You also need a fuse or circuit breaker in the positive side otherwise a jam in the pump could start a fire.

Several different ways to wire an alarm. Depends on what you're trying to do. Do you want the alarm to go off every time this pump comes on?

You need a three-way switch and a float switch if you want the pump to be automatic.

The attached shows a warning light, it could be an alarm.

Thanks for your reply, I forgot to mention that the float switch is separate. Also if I want to buy the alarm and the light, what it is called, when I ask a marine sales person like defender.com for example.

If your Rule has a separate float switch then the wiring diagram from Ex-Calif is exactly what you need. If you want a light then any 12V panel light would do the job.

So how would that diagram look with the 1,2 all off switch involved?
Would you even involve that switch?
