Question about Attwood Sahara Bilge Pump 500 GPH

1 Answer

I'm getting 12v to the wiring in the bilge but the pump will not turn on. It will turn on when connected at the battery. The wiring runs from the switch panel through the bulk head and panels so it's not very accessible. This is on a Hunter H260.

I want to put a toggle switch in line so that I can switch my camping shower on and off. It runs from a bilge pump in a bucket of water

1. locate where you want the switch (such as inside the RV or on a stake that can be placed near the shower enclosure)
2. If the pump runs on 120 volts make sure the location of the switch is not going to get wet or it may be your last shower ever. If the pump is 120 volts (house current) it may be safer to run an extension cord to the pump and just plug the pump in from the inside of the RV when you take a shower.
3. If the bilge pump is 12 volts just get an on/off toggle and run wires from the toggle switch to the battery and then the red (positive) wire on the pump.

Wiring bilge float switch

The float switch is normally wired to turn on by itself. To do this, you simply run a "hot" lead from the battery to the float switch, then from the float switch to the bilge pump. It is best if this wire has a fuse between the battery and the pump! The "negative" or ground side should already be supplied if the pump is hooked up to a switch on the dash board. IF there is not switch on dash, you may have to run a ground wire directly to the pump.

What is a 12v acc.

1.Wire name: ACC wire
Color: Red
Describtion of ACC wire:
When you insert key into ignition switch and turn it to the left you are turning on the ACC circuit. It will allow you to operate radio, windows and other accesories, but it does not turn on fuel pump and other engine controls. It saves battery power for when you need to operate vehicle components without engine being on.
The ACC wire offers power/electricity only when you insert car key into ignition switch and turn it to the left
The ACC wire needs to be connected to car igniton
2.Wire name: 12V battery(+)
Color: Yellow
Describtion of 12V battery(+) wire:
The 12V permanent battery wire will always offer power/electricity when the vehicle is turned on or off
The 12v permanent battery wire needs to be connected to car battery.

I need the wiring diagram for the wiring on my Princecraft DLX Restorer boat. My marine lights, livewell and bilge pump are not working.

No such animal exists. They are not wired via a diagram at the factory. Your best bet is a simple light up circuit tester which are only a couple bucks at places like Harbor Freight. All auto stores will have them as well. Then just follow the wiring from each component switch (turned on) to any splices, fuse panel, etc. and see where it is powered and where it is not. You should be able to isolate it. Since you have 3 components not working, I would start at junctions where multiple wires connect such as Ground, fuse panel, behind dash, etc.

Sounds like the pump is cooked, probably need a new one. Also check the switch on the dash, sounds like it might have failed leading to over running the pump dry, overheating the motor causing a short in the motor somewhere. Boat electrics need regular maintenance, looking behind the panel with some switch cleaner in your hand is a good idea.

I'm trying to wire a 12v bilge manual pump to a

You run your hot wire to the switch (brown) and black wire to the pump (+ve connection). Then from the pump run another wire to the negative terminal of your battery. I used to use a toggle switch on mine, but I do not use a starter motor, still all the lights, radio and echo sounder are connected to it (via a junction box). The only item I fuse is my echo sounder.

Wiring on bilge pump

There's an installation manual available online. Black is negative ground; either brown or brown/white will turn on the pump. The intent is for a three way switch, connecting brown/white directly to positive 12 VDC while brown would go through an automatic switch (e.g., a float switch).

No Power to Fuel pump

I would check the ground for the fuel pump relay that operates the switch side of the relay.
You should have 2 12v inputs to the relay. When the relay gets 12v input, it closes the relay switch on the heavy current side that sends 12v to the fuel pump.

A relay is needed because you don't want heavy current going through the switch.

Also, most cars only run the fuel pump for 2 seconds when the key is turned on because you don't want the fuel pump running without the car running. If you listen closely at the fuel tank, you should hear the pump run for 2 seconds when you turn the key to "ON"
When the key is turned to "START", the fuel pump should run continuously.
The engine computer tells the fuel pump to shut off if the engine rpms are zero.
So, I would check the switch side of the relay. Power amd ground.
