Multiquip 31630ZE2861 Coil Assy Charge (1A) GX390 - OEM Replacement Part

The Coil Assy Charge provides 1 amp charging capability for the GX390 engine's electrical system, powering the battery and electromagnetic clutch system on vibratory rollers. This charging coil is critical for maintaining proper voltage to the 12V DC electromagnetic clutch that controls the vibration system, which requires consistent power delivery to prevent improper actuation or absorption issues.

On the MRH800GS vibratory roller, the electromagnetic clutch operates at a rated voltage of 12V DC with 6.6 ohms coil resistance at 68°F. The charging coil ensures adequate current flow to maintain clutch engagement while protecting against over-amperage conditions through the 5A fuse in the wire harness. If the charging system fails, operators may experience loss of vibration function while the engine continues running at 2,500 rpm, as the clutch system does not affect travel operation.

Compatible models:

• MRH800GS (with GX390 engine variants)
