JZGRDN 36V 350A 5-Pin Speed Controller for E-Z-GO TXT/Medalist – Direct-Fit 1206-Series Replacement

JZGRDN's 36V 350A 5-pin speed controller replaces OEM 1206-series controllers to restore smooth torque and throttle response on compatible E-Z-GO TXT and Medalist golf carts.

This heavy-duty controller is designed for E-Z-GO TXT and Medalist carts with ITS throttle input and three big motor blades — it supplies up to 350 amps at 36 volts and fits the 1206-series (non-DCS) 5-pin configuration. Built as a direct-fit aftermarket alternative for many model years, it supports reliable acceleration control for utility and leisure use when the original controller fails or needs upgrading. Before purchasing, confirm your cart uses a 5-pin controller and a non-separately-excited motor; this unit is not compatible with DCS or 9-pin systems.

How do I know this controller fits my E-Z-GO cart?

Check your cart's control module part number and connector type. This unit matches 1206-series (non-DCS) controllers that use a 5-pin ITS throttle input and motors with three large blades. Confirm the existing controller part numbers listed in the product features or compare the physical connector.

• Fits E-Z-GO TXT and Medalist models using 5-pin 1206 series controllers.
• Compatible with part numbers like 1206-4301 and 25864G09 among others.
• Not compatible with DCS or 9-pin controllers — verify connector count first.
• Works with carts from model years 1994 through 2019 listed in features.

What electrical performance and limits should I expect?

This controller provides control for 36V electrical systems with a peak capability around 350 amps, optimized for golf-cart motors matched to the ITS throttle input. It handles normal start, acceleration, and regenerative behaviors that the original OEM unit would manage, within the specified voltage and current range.

• Designed for 36V battery systems common in E-Z-GO TXT and Medalist carts.
• Rated around 350A to manage motor torque demands safely.
• Engineered for motors with three large blades (not Sep Ex motors).
• Non-DCS architecture — ensure system compatibility before install.

What should I check before installing this controller?

Verify connector pin count, motor type, and part-number cross-references to avoid incompatible swaps. Also confirm mounting dimensions and that your cart uses ITS throttle input. If you aren’t sure, compare the old controller’s printed part numbers or take a photo of the harness to match against the product listing.

• Confirm you have a 5-pin controller connector, not a 9-pin or DCS unit.
• Ensure the motor is not a separately excited (Sep Ex) or shunt-wound design.
• Cross-check OEM numbers like 1206-4301, 25864-G03, 25864G09, and related aliases.
• Contact the seller if you need a 9-pin variant or doubt compatibility.

How does this controller affect cart performance day-to-day?

When fitted correctly, the controller restores predictable acceleration and throttle modulation, helping the cart respond consistently under load. It provides stable current management during starts and climbs, returning the original driving characteristics without requiring major electrical changes.

• Improves throttle response compared with a failing controller.
• Maintains factory-style acceleration and load handling for 36V systems.
• Plug-and-play replacement for matching 1206-series units when mounting and connectors align.
• Reduces downtime by replacing aging or damaged OEM electronics quickly.

Who is this for: This JZGRDN 36V 350A 5-pin speed controller is aimed at owners and technicians of E-Z-GO TXT and Medalist golf carts (model years listed) who need a like-for-like replacement for a failed 1206-series controller. It suits users comfortable verifying electrical compatibility and performing straightforward controller swaps or hiring a technician for installation. If your cart uses a 9-pin DCS controller or a separately excited motor, seek a different part or contact us for guidance.
