The Multiquip 31750Z2E803 is a genuine OEM Rectifier Assembly Regulator 20A designed for JWN24HTCSL, JWN24HSCSL, WTB-16, and WTB-16PD series equipment. As a factory-sourced component, this rectifier assembly is built to the exact electrical specifications of the original unit, ensuring correct output regulation and reliable charging system performance. Verify your model code before ordering to confirm fitment with your specific machine configuration.

Key Features

  • Correct 20A Output Rating — Matched to the original electrical specification, ensuring the charging circuit operates within the designed current threshold for these machines.
  • Genuine OEM Component — Sourced directly from Multiquip, this assembly meets the same tolerances and materials as the part it replaces — no guesswork on compatibility.
  • Direct-Swap Installation — Connects to the existing wiring harness using the original mounting configuration, so replacement stays straightforward.
  • Broad Model Coverage — Fits JWN24HTCSL/HSCSL walk-behind trowels and WTB-16/WTB-16PD track power buggies, making it a useful stock item across multiple machine types.
  • Electrical System Protection — A properly functioning regulator rectifier prevents overcharging and voltage spikes that can damage the battery, ignition components, and onboard electronics.
  • Critical Charging System Safety — A failed regulator can cause uncontrolled voltage output, creating risk of electrical damage or unexpected shutdowns during operation — replacing promptly with the correct OEM part keeps the electrical system operating safely.

The regulator rectifier serves two functions in one assembly: it converts AC output from the engine's alternator into usable DC current, and it regulates that voltage to protect the battery and electrical components from overcharge. When this part fails, the machine may experience a dead battery, erratic electrical behavior, or components drawing unregulated current. Replacing a worn or failed rectifier assembly with the correct-rated unit restores proper charging function and protects the rest of the electrical system from downstream damage.
