the Dual Resistor Kit for the 2018 E-Z-GO RXV Shuttle 2+2

1. Overview of the E-Z-GO RXV Shuttle 2+2

The E-Z-GO RXV Shuttle 2+2 is a reliable electric vehicle commonly used for transportation in large spaces, such as resorts, parks, campuses, and golf courses. This model, particularly popular for its electric performance and low maintenance needs, comes with regenerative braking, which captures energy during braking and recharges the battery.

However, in situations involving steep downhill travel, this regenerative feature may inadvertently overcharge the batteries, leading to overheating. Here’s where the Dual Resistor Kit steps in as an essential upgrade.

2. What is the Dual Resistor Kit?

The Dual Resistor Kit (Part No. 686593) is an upgrade designed for E-Z-GO RXV electric models (2008–2024). This kit includes:

• Two resistors mounted in parallel,
• A mounting bracket,
• A wiring harness, and
• Necessary installation hardware.

It replaces the stock single resistor, improving the vehicle’s ability to dissipate excess energy as heat, especially beneficial in hilly or downhill environments where regenerative braking produces surplus energy.

3. Why Install a Dual Resistor Kit?

Key Benefits:

• Improved Heat Dissipation: Two resistors work more efficiently than one, allowing better heat management when excess energy is produced.
• Enhanced Performance in Hilly Terrains: Prevents the risk of system shutdown during prolonged or steep downhill driving by distributing excess energy more effectively.
• Increased Battery Protection: Prevents overcharging of fully charged batteries, which can lead to overheating and reduce battery life.
• Extended System Longevity: With more consistent energy management, the system experiences less wear, enhancing reliability.

Installing this kit not only improves the E-Z-GO RXV’s safety and performance but also extends its overall life, making it an ideal addition for vehicles frequently used in challenging terrains.

4. Installing the Dual Resistor Kit: A Step-by-Step Guide

Note: It’s recommended to follow E-Z-GO’s safety guidelines and use insulated tools. If you are unfamiliar with electrical systems, consider professional assistance.

Tools Needed:

• Wrenches or socket set
• Screwdrivers
• Insulated gloves
• Multimeter (for voltage testing)

Installation Steps:

1. Preparation:
   • Park the vehicle on a level surface, ensuring it’s powered off.
   • Disconnect the battery to prevent accidental electric shocks during the installation.
2. Access the Current Resistor:
   • Locate the existing resistor in your E-Z-GO RXV model. For most models, it is installed near the controller area.
   • Remove any covers or mounting bolts to access the resistor.
3. Remove the Single Resistor:
   • Carefully disconnect the wiring connected to the existing resistor.
   • Unbolt the resistor and set it aside. Ensure you keep the hardware organized if you plan to repurpose any for the new installation.
4. Install the New Mounting Bracket:
   • Place the new mounting bracket included with the Dual Resistor Kit.
   • Secure the bracket firmly to provide a stable platform for the two resistors.
5. Attach the Dual Resistors:
   • Mount each resistor onto the bracket.
   • Ensure the resistors are securely fastened to handle vibrations during vehicle movement.
6. Connect the Wiring Harness:
   • Attach the wiring harness to both resistors, following the instructions provided in the kit.
   • Ensure connections are secure, and there are no loose wires that could cause short circuits.
7. Testing the Installation:
   • Use a multimeter to check connections for continuity.
   • Reconnect the battery, and turn on the vehicle.
   • Test drive the vehicle on a downhill slope to check if the resistors are managing heat effectively without overheating.

5. Frequently Asked Questions (FAQs)

Q1: Can I install the Dual Resistor Kit on my own?
A: Yes, if you have basic electrical knowledge and feel comfortable working with vehicle components. However, for best results, professional installation is recommended.

Q2: How do I know if my E-Z-GO RXV needs a Dual Resistor Kit?
A: If you frequently drive on steep hills or experience system shutdowns during downhill travel, the Dual Resistor Kit can be an effective solution.

Q3: Will installing this kit void my warranty?
A: Installation may not void the warranty if done correctly, but always check with E-Z-GO or your authorized dealer for confirmation.

6. Maintenance Tips After Installation

After installing the Dual Resistor Kit, perform regular maintenance to ensure optimal performance:

• Inspect the resistors monthly for wear, especially if used in high-energy-demand situations.
• Check connections periodically to ensure they remain tight and free from corrosion.
• Clean the area around the resistors to prevent debris buildup, which can affect heat dissipation.

7. Final Thoughts

The Dual Resistor Kit for the E-Z-GO RXV Shuttle 2+2 provides an effective way to enhance performance in terrains with elevation changes. It is a valuable investment for those looking to extend the life of their electric vehicle, protect their battery, and prevent shutdowns due to overheating.

By following this guide, you can install the kit safely and ensure your E-Z-GO RXV operates smoothly, even in demanding conditions.
