If you’re looking to upgrade your trolling motor, you may be wondering how to wire a 36 volt trolling motor. With a few basic tools and some knowledge of electrical wiring, it’s easy to install a 36 volt trolling motor on your boat. In this article, we’ll walk you through the process step-by-step and provide you with a helpful diagram to make the process as easy as possible.
What is a 36 Volt Trolling Motor?
A 36 volt trolling motor is a high-powered motor that is used to propel your boat through the water. The higher voltage allows for greater speed and increased power, making it ideal for larger boats or those that require more propulsion. Most 36 volt trolling motors are designed for use with deep cycle marine batteries, which are specifically designed to provide a steady current over a long period of time.
What are the Benefits of a 36 Volt Trolling Motor?
There are several benefits to using a 36 volt trolling motor over a lower voltage model. Some of the most significant benefits include:
- Increased power
- Greater speed and acceleration
- Increased battery life
- Improved performance in rough water
What Tools Do I Need to Wire a 36 Volt Trolling Motor?
Before you get started, you’ll need to make sure you have the following tools:
- Wire cutters/strippers
- Soldering iron (optional)
- Heat gun (optional)
- Crimping tool
- Electrical tape
- Wire connectors
- 36 volt trolling motor wiring diagram (provided below)
Step-by-Step Guide for Wiring a 36 Volt Trolling Motor
Now that you have all of the necessary tools, it’s time to get started. Follow these step-by-step instructions to wire your 36 volt trolling motor:
Step 1: Disconnect the Battery
Before you begin any electrical work, it’s important to disconnect the battery to prevent any electrical shock or short circuits. Make sure the main power switch is off and disconnect the positive and negative terminals from the battery.
Step 2: Prepare the Wires
Using your wire cutters/strippers, cut the wires to the appropriate length and strip the ends to expose the copper wire. If necessary, use a soldering iron and heat gun to secure any loose strands and create a solid connection before crimping the connectors in place.
Step 3: Connect the Batteries in Series
For a 36 volt trolling motor, you’ll need to connect three 12 volt marine batteries in series. This means that the positive terminal of one battery is connected to the negative terminal of the next battery, and so on. Follow the diagram below to make sure you connect the batteries in the correct order.
| Battery 1 | Battery 2 | Battery 3 |
|---|---|---|
| Positive (+) | Negative (-) | Positive (+) |
| Negative (-) | Positive (+) | Negative (-) |
Step 4: Connect the Trolling Motor Wires
Once the batteries are connected in series, it’s time to connect the trolling motor wires. Follow the diagram below to make sure you connect the wires in the correct order.
| Trolling Motor Wires | Battery Wires |
|---|---|
| Red (+) | Positive (+) on Battery 1 |
| Black (-) | Negative (-) on Battery 3 |
Step 5: Test the Motor
Once you’ve connected all of the wires, it’s important to test the motor before you hit the water. Turn on the main power switch and test the motor at the lowest setting to make sure it’s working properly. If everything is working as it should, you’re ready to hit the water!
FAQ About Wiring a 36 Volt Trolling Motor
Q: Can I wire a 36 volt trolling motor with less than three batteries?
A: No, a 36 volt trolling motor requires three 12 volt marine batteries wired in series to provide the correct voltage and amperage.
Q: Can I use any type of battery with a 36 volt trolling motor?
A: No, you should only use deep cycle marine batteries that are designed to provide a steady current over a long period of time. Using other types of batteries can damage your trolling motor and reduce its performance.
Q: Can I install a 36 volt trolling motor myself?
A: Yes, installing a 36 volt trolling motor is a fairly simple process that can be completed with basic tools and some knowledge of electrical wiring. Just be sure to follow the instructions carefully and take all necessary safety precautions.
Q: What is the maximum amperage for a 36 volt trolling motor?
A: The maximum amperage for a 36 volt trolling motor will depend on the specific model and manufacturer. It’s important to check the motor’s specifications and make sure your batteries are capable of delivering the necessary amperage.
Q: What is the maximum speed for a 36 volt trolling motor?
A: The maximum speed for a 36 volt trolling motor will vary depending on the size of your boat and the specific motor you choose. Most 36 volt trolling motors are capable of speeds between 5 and 10 miles per hour.
Conclusion
Wiring a 36 volt trolling motor may seem daunting at first, but with the right tools and a good understanding of electrical wiring, it’s a relatively simple process. Just be sure to follow the instructions carefully and take all necessary safety precautions to ensure a successful installation. With a 36 volt trolling motor, you’ll enjoy increased power, greater speed, and improved performance on the water.
