36 Volt Trolling Motor Battery Wiring Diagram

When it comes to fishing, having a reliable trolling motor is a must. However, even the best trolling motor won’t be able to function without a properly wired battery. In this article, we’ll walk you through the process of wiring a 36 volt trolling motor battery with a detailed diagram and FAQ section.

Why Do I Need a 36 Volt Trolling Motor Battery?

A 36 volt trolling motor requires a battery that can supply the necessary power to operate. Typically, two or three 12 volt batteries are used in series to create the 36 volts required. This allows for a longer operating time and better performance compared to a 24 volt motor.

Wiring a 36 volt trolling motor battery may seem like a daunting task, but it can be done with a little patience and attention to detail. The first step is to gather all the necessary materials and tools for the job.

Materials and Tools Needed

Materials Tools
Two or Three 12 Volt Batteries (depending on trolling motor) Soldering Iron
Battery Terminal Connectors Wire Crimper
Wire (preferably 6 gauge) Wire Strippers
Electrical Tape Heat Shrink Tubing
Wire Brush
Wrench

Before starting the wiring process, it’s important to make sure that all the batteries are fully charged and in good condition. Also, ensure that you’re working in a well-ventilated area away from any flammable materials to prevent any accidents.

Wiring a 36 Volt Trolling Motor Battery

Now, let’s get started with the wiring process. Follow these steps carefully to avoid any mishaps along the way:

Step 1: Disconnect the trolling motor from the power source and remove any existing wiring from the batteries.

Step 2: Place the batteries in series by connecting the negative terminal of the first battery to the positive terminal of the second battery. Repeat for the remaining batteries until all of them are connected in series.

Step 3: Install the battery terminal connectors onto the battery terminals. Ensure that the connectors are tight and secure.

Step 4: Cut four lengths of wire, each long enough to reach from the trolling motor to the battery connections. Strip about an inch of insulation from both ends of each wire.

Step 5: Connect the wires to the battery terminals following this pattern: Connect the positive terminal of the first battery to the positive input of the trolling motor. Connect the negative terminal of the second battery to the positive terminal of the first battery. Connect the negative terminal of the third battery (if applicable) to the positive terminal of the second battery. Finally, connect the negative input of the trolling motor to the negative terminal of the last battery in the series.

Step 6: Use the wire brush to clean any corrosion or debris from the battery terminals and connectors. Cover the connections with electrical tape to prevent any accidental shorts.

Step 7: Solder and heat shrink any crimped connections for added durability and reliability.

Step 8: Reconnect the trolling motor to the power source and test the motor to ensure that it’s working properly.

Once you’ve completed these steps, you can rest assured that your 36 volt trolling motor battery is properly wired and ready for use.

FAQ

  1. What is the difference between a 24 volt and 36 volt trolling motor?
  2. A 36 volt trolling motor uses three 12 volt batteries in series to provide more power and a longer operating time compared to a 24 volt motor which uses two 12 volt batteries.

  3. What type of wire is best for wiring a 36 volt trolling motor battery?
  4. It’s recommended to use 6 gauge wire for wiring a 36 volt trolling motor battery as it can handle the high amperage required and minimize voltage drop.

  5. Can I use different types of batteries in a 36 volt trolling motor?
  6. No, it’s not recommended to mix different types of batteries in a series as it can lead to uneven charging and damage to the batteries. Use the same type of battery with the same capacity and age for the best performance.

  7. Can I wire a 36 volt trolling motor with just two batteries?
  8. No, a 36 volt trolling motor requires three 12 volt batteries connected in series to provide the necessary power.

  9. Should I disconnect the batteries when not in use?
  10. Yes, it’s recommended to disconnect the batteries when not in use to prevent any parasitic drain or accidental short circuits.
