Multiquip 31600ZE2861 Regulator Assy GX390 - OEM Replacement Part for Vibratory Rollers

The regulator assembly controls voltage output from the charging system on Honda GX390-powered vibratory rollers, ensuring stable electrical power for critical components like the electromagnetic clutch and battery charging system. This is essential for proper operation of the vibration system, which relies on consistent 12V DC power to engage the electromagnetic clutch rated at 6.6 ohms coil resistance.

On equipment like the MRH800GS vibratory roller, electrical system stability is critical for the electromagnetic clutch that activates the vibration mechanism. The clutch operates at 12V DC with a rated torque of 25 Nm (2.5 kgf-m), and any voltage irregularities can lead to improper actuation or failure to engage. A failing regulator can cause over-amperage conditions that blow the 5A fuse in the wire harness, resulting in loss of vibration capability while the roller continues to travel at 2,500 rpm engine speed.

Compatible with the following Multiquip models:

• MRH800GS
• PRO12/PRO12E51
• PRO12C/PRO12E51C
