FBULWSEC 36V EZGO Powerwise Charger Replacement Board — Control & Power Input Module, Fits OEM 28667G01

FBULWSEC 36 Volt EZGO Powerwise Charger Board is a direct replacement control and power-input circuit assembly for 1994-and-newer EZGO Powerwise chargers.

If your EZGO Powerwise charger shows faults, won't start, or charges intermittently, this factory-compatible 36V replacement board restores the charger’s control logic and power-input functions. Designed to replace common OEM part numbers (28667G01, 28566G01, 28566-G01, 28566-G03, 28126-G01, 28667-G01, 28126GO3), the assembly integrates both the control PCB and the power input section so you can swap one module instead of two. The listing is for the electronic board only; installation requires basic electrical troubleshooting skills and safe handling of powered equipment.

Will this board fit my EZGO Powerwise charger?

This board is built to match the mounting points, connector types, and voltage range used in EZGO Powerwise chargers from 1994 onward. Confirm compatibility by comparing part numbers and visual connection points before purchase.

• Replaces OEM numbers: 28667G01, 28566G01, 28566-G01, 28566-G03, 28126-G01, 28126GO3
• Designed for 36V Powerwise charger models
• Matches factory PCB layout and terminal locations for a direct swap

How do I install the replacement control and power-input board?

Installation typically involves removing the charger cover, documenting wiring positions, disconnecting the old boards, and securing the new assembly in place. Always disconnect mains power and battery connections before working on the charger to avoid shock or damage.

• Power down and unplug charger; disconnect battery first
• Take photos of wiring or label cables for correct reconnection
• Swap boards, reconnect harnesses, and verify secure mounting

What troubleshooting should I do after replacement?

Once installed, test the charger with a known-good 36V battery pack and monitor voltage and relay operation. If the relay does not engage, verify battery open-circuit voltage and wiring; note the relay may not operate below a threshold voltage.

• Check charger output voltage with a meter under no-load conditions
• Confirm relay operation and LED indicators function as expected
• If relay fails to engage, ensure battery voltage is above 28V and connections are clean

Are there any important limitations or safety notes?

The replacement board restores control and power input circuits but does not include external housing, fuses, or other mechanical parts. It is intended for trained hobbyists or technicians who can safely work with mains and battery voltages.

• Relay may not activate if battery voltage drops below 28V
• Handle ESD-sensitive components with grounding precautions
• Do not operate charger with missing safety covers or damaged wiring

Who this is for: This FBULWSEC 36V replacement board is suited for golf cart owners, fleet technicians, and repair shops that maintain EZGO Powerwise 36V chargers. If you need a like-for-like electronic replacement to restore charging function and prefer a single assembly that replaces both control and power input boards, this part simplifies repairs and reduces downtime. If you’re unsure about compatibility or lack the tools to safely perform the swap, consult a qualified technician or the cart manufacturer for guidance.
