The Multiquip 31750Z2E802 Rectifier Assembly Regulator 20A is a genuine OEM component designed for AR13HA series asphalt ride-on rollers. As a direct OEM replacement, this part meets the original electrical specifications required to keep your roller's charging system operating correctly. Sourced directly through authorized channels, 31750Z2E802 is the correct replacement for AR13HA and AR13HAR equipped machines.
Key Features
- OEM-Rated Electrical Output: — Engineered to the original 20A output specification, ensuring correct charge delivery to the battery and no risk of undercharging or overcharging the electrical system.
- Direct Plug-In Replacement: — Designed to mount and connect exactly as the original unit, using the same bracket points and wiring harness connectors found on AR13HA rollers.
- Confirmed Fitment for AR13HA Series: — Verified for AR13HA and AR13HAR asphalt ride-on roller models, so you can order with confidence.
- Protects the Full Charging Circuit: — A functioning rectifier-regulator converts and stabilizes AC output from the alternator into usable DC power; a failed unit can leave the machine unable to start or cause premature battery failure.
- Electrical Safety Compliance: — Running a roller with a faulty or out-of-spec rectifier-regulator can cause voltage spikes that damage other electrical components; replacing with a genuine OEM unit restores safe operating voltage across the system.
The rectifier assembly regulator serves a critical role in the roller's electrical system. It converts the alternating current produced by the engine's alternator into the direct current needed to charge the battery and power onboard electrical components, while also regulating voltage to prevent dangerous spikes. When the rectifier-regulator fails or degrades, the battery will no longer charge correctly, leading to hard-starting conditions, electrical faults, and potential damage to other components in the charging circuit.
