Restore Power & Smooth Control to Your Golf Cart

If your golf cart shows slow acceleration, jerky movement, or loss of power, your controller may be worn or failing.

The 10L0L 36V 300A Speed Controller is designed to restore smooth acceleration, stable power delivery, and reliable driving performance, especially for older EZGO TXT and Medalist models.

Key Features

Direct Curtis 1206SX Replacement

• Plug‑and‑play – replaces Curtis 1206SX‑005, 73144G01, 73144G02, 73144G03, 73144G04, 73144G06.

• Same 9‑pin connector (10 slots with 1 empty) and 5‑terminal configuration.

• No reprogramming needed for basic operation.

Exact Fit for 1995-2000 EZGO with DCS

• Designed for EZGO TXT and Medalist models from 1995 through 2000.

• Requires DCS (Drive Control System) and SepEx (Separately Excited) motor.

• Does not fit series-wound motors or PDS models (1996‑2000 with rocker switch).

36V 300A SepEx Motor Controller

• Voltage: 36V DC | Current: 300A (max).

• Provides stable control for start, acceleration, and deceleration.

• Compatible with ITS throttle input (standard for DCS carts).

Terminal & Connector Specifications

Built‑In Safety Protections

• Overcurrent protection – prevents damage from excessive current draw.

• Short circuit protection – shuts down output in case of wiring fault.

• Overheating protection – reduces power or shuts off if internal temperature exceeds safe limit.

• Extends the life of your controller and protects your cart’s electrical system.

Excellent Service & Support

• Direct bolt‑on replacement – no complicated wiring.

• Our team is available to answer fitment or installation questions.

Important Compatibility Notes

⚠️ How to verify your cart has DCS: Look for a 9‑pin connector at the controller and a run/tow switch (typically on the controller cover). If your cart has a rocker switch (FNR) on the dash, it is likely PDS – this controller will not work.

Why Replace Your Controller?

A failing or mismatched controller can cause:

• Intermittent or no movement – solenoid clicks but cart won’t go.

• Jerky acceleration or sudden stops – especially on hills.

• Reduced torque – struggles to climb inclines.

• Error codes or beeping from the cart’s diagnostic system.

Installing a fresh 10L0L 36V 300A controller restores factory correct performance and adds modern protection features.

Installation Overview

🔧 Moderate DIY skill recommended – always disconnect batteries before working on electrical components.

1. Disconnect the battery pack (positive and negative terminals).

2. Remove the old Curtis controller – label wires if needed (take a photo of the original connections).

3. Install the new 10L0L controller in the same mounting location.

4. Connect large terminals:

   • A1 → motor armature

   • B‑ → battery negative

   • A2/B+ → battery positive or motor armature (depending on your cart – consult diagram)

5. Connect small terminals: F1 and F2 to motor field wires (polarity matters – match original).

6. Plug in the 9‑pin connector (ensure it seats fully).

7. Reconnect batteries, set Run/Tow switch to “Run”, and test – smooth acceleration in forward and reverse.

📘 Professional installation recommended if you are not familiar with DC motor controllers. Always follow safety procedures to avoid electrical shock or damage.
