If you own a boat, you know the importance of a good bilge pump. A bilge pump is responsible for keeping your vessel afloat by removing excess water from the bilge. However, a bilge pump won’t do you any good if it’s not properly wired. In this article, we will provide you with a comprehensive guide on how to wire a 12-volt bilge pump.
What Is a Bilge Pump?
A bilge pump is a mechanical device that is designed to remove water from the bilge of a boat. The bilge is the lowest part of a boat’s hull, where water collects. Excess water in the bilge can cause the boat to sink or become unstable.There are two types of bilge pumps: manual and automatic. A manual bilge pump is operated by hand, while an automatic bilge pump is connected to a sensor that detects water in the bilge and turns on the pump automatically.
Manual Bilge Pump
A manual bilge pump is ideal for small boats or as a backup option. To operate a manual bilge pump, you need to pump a handle up and down to remove water from the bilge. Manual bilge pumps can be portable or fixed in place.
Automatic Bilge Pump
An automatic bilge pump is the most popular type of bilge pump for boats. It is designed to turn on automatically when water is detected in the bilge. Automatic bilge pumps are available in various sizes and can be installed in different locations.
How to Wire a 12 Volt Bilge Pump
Wiring a 12-volt bilge pump is a relatively easy task that can be done by anyone with basic electrical knowledge. Here are the steps to follow:
Step 1: Gather Your Tools and Materials
To wire a 12-volt bilge pump, you will need the following tools and materials:
- 12-volt bilge pump
- Bilge pump switch
- Primary wiring (red and black)
- Bilge pump hose
- Fuse holder
- Fuse (3-amp or 5-amp)
- Crimping tool
- Screwdriver
- Wire stripper
Step 2: Install the Bilge Pump Switch
The bilge pump switch is used to turn the pump on and off manually. Install the switch in a convenient location, such as the control panel or near the helm.
Step 3: Connect the Wiring
Connect the wiring as follows:
- Connect the red wire from the bilge pump to the positive (+) terminal on the battery.
- Connect the black wire from the bilge pump to the negative (-) terminal on the battery.
- Connect the positive (+) wire from the bilge pump switch to the positive (+) terminal on the battery.
- Connect the negative (-) wire from the bilge pump switch to the negative (-) terminal on the battery.
- Connect the fuse holder to the positive (+) wire from the bilge pump switch.
- Insert the fuse into the fuse holder.
Step 4: Install the Hose
Install the hose from the bilge pump to the through-hull fitting. Make sure the hose is secured properly to prevent leaks.
FAQ
Q: What size bilge pump do I need?
A: The size of the bilge pump you need depends on the size of your boat. Generally, it is recommended to use a bilge pump with a capacity of at least 500 gallons per hour (GPH) for small boats.
Q: Can I wire a bilge pump directly to the battery?
A: Yes, you can wire a bilge pump directly to the battery. However, it is recommended to use a fuse to protect the wiring in case of a short circuit.
Q: How often should I check my bilge pump?
A: It is recommended to check your bilge pump at least once a month, especially before heading out on a trip. Make sure the pump is working properly and the hose is not clogged.
