Multiquip 31750Z6L004 Rectifier Regulator Assembly - OEM Replacement Part

This rectifier regulator assembly controls and stabilizes the electrical charging system on Multiquip vibratory ride-on rollers, converting AC current from the alternator to regulated DC power for the battery and electrical components. Critical for maintaining proper voltage to prevent electrical system damage, this component protects sensitive electrical motors and wiring throughout the machine—particularly important given the AR14H's electrical water pump system and associated wiring vulnerability documented in service bulletins. The rectifier assembly ensures consistent power delivery to operate the machine's hydraulic control systems, vibratory functions, and water suppression system.

Failure symptoms include electrical shorts, inconsistent charging, battery drain, or electrical motor malfunctions. Given the AR14H's documented water intrusion issues affecting electrical components, maintaining a properly functioning voltage regulation system is essential for preventing costly damage to the water pump motor and other electrical systems.

Compatible with the following Multiquip models:

• AR14H Vibratory Ride-On Roller
