BHB 36V 350A Cart Motor Controller for EZGO TXT 2000–2009 — ITS Throttle, Direct-Fit Curtis 73326 Replacement

BHB's 36V 350A motor controller replaces Curtis 73326-style units to restore precise speed and torque control on EZGO TXT golf carts (model years 2000–2009).

If your EZGO TXT shows sluggish acceleration, inconsistent throttle response, or electrical faults tied to the original Curtis 73326 series controller, this BHB direct-fit replacement provides a modern, cost-effective solution. Designed to match the original mounting and electrical pinout, the controller supports ITS throttle type, advanced PWM motor management, and a 350A current rating suitable for stock 36V systems.

How does this controller improve my EZGO TXT's throttle and acceleration?

The BHB controller uses refined pulse-width modulation (PWM) to deliver smoother, more consistent power to the motor across the throttle range. That reduces abrupt surges and helps maintain steady acceleration under load without changing your battery configuration.

• Advanced PWM lowers torque conversion losses for better efficiency.
• Smoother throttle mapping reduces jerky starts and stops.
• 350A current capability supports normal hill-climbing and two-up loads.

Will this unit fit my golf cart and replace the Curtis 73326 models?

Yes — the BHB controller is built around the same form, mounting points, and electrical layout as the Curtis 73326 family to simplify installation. It lists compatibility with multiple Curtis and EZGO part numbers commonly used on TXT chassis from 2000–2009.

• Compatible with Curtis: 73326-G02, 73326G02, 73326G04, 73326G05, 73326G06, 73326G07.
• Fits EZGO replacement numbers 73326G02–73326G08 and related OEM references like 609083.
• Designed to work with ITS throttle configurations on 36V systems.

What are the key electrical specs and protections I should know?

This controller is rated for a nominal 36V battery pack and continuous 350A current handling, suitable for standard TXT motors and typical accessory loads. Built-in motor and vehicle control coordination helps prevent mismatched commands, and the firmware supports user-side program concurrency for stable operation.

• Nominal battery voltage: 36V, Current rating: 350A.
• Throttle interface: ITS (industry throttle standard) compatible.
• Works with vehicle-side programs and motor-control routines concurrently to prevent conflicts.

How difficult is installation and what should I check before buying?

Installation is usually straightforward for a technician or experienced DIYer familiar with golf-cart electrical systems. Verify your existing controller's part number, connector layout, and throttle type before ordering, and disconnect batteries during replacement for safety.

• Confirm original part number (Curtis 73326 series or EZGO 73326Gxx) matches your unit.
• Check connector and mounting holes align with the BHB controller footprint.
• Disconnect batteries and note wire locations or photograph connections before removal.

Who is this for: This BHB 36V 350A controller is aimed at EZGO TXT owners (2000–2009) repairing or upgrading a failed Curtis 73326-style unit, fleet managers maintaining multiple carts, and DIY mechanics seeking a cost-effective OEM-compatible replacement. It suits carts that use ITS throttle interfaces and standard 36V motor setups, offering a practical balance of correct fitment, robust current capacity, and improved PWM efficiency without rewiring or major system changes.
