The Wacker Neuson Voltage Regulator is a genuine OEM component designed for the HI 770 XHD Indirect Air Heater series and Arctic Bear XHD heaters. As a direct OEM replacement, this part is manufactured to the exact specifications of the original, ensuring it integrates seamlessly into your heater's electrical system without guesswork or adaptation. Confirmed fitment spans multiple HI 770 XHD configurations — including diesel models with 1x16, 1x20, and 2x12 duct setups — as well as Extra Heavy Duty Air Heater variants and the Arctic Bear XHD. Keeping the correct voltage regulator in service is essential to maintaining stable electrical output and protecting the heater's sensitive components from power fluctuations.
Key Features
- Correct Output Specification: — Genuine OEM construction ensures the regulator delivers the precise voltage output your heater's electrical circuits require — no under- or over-voltage risk.
- Drop-In Electrical Replacement: — Matches the original connector configuration and mounting profile for a straightforward swap into the existing wiring harness.
- Broad HI 770 XHD and Arctic Bear XHD Coverage: — Verified for multiple HI 770 XHD diesel configurations (1x16, 1x20, 2x12) and Arctic Bear XHD and Extra Heavy Duty Air Heater variants.
- Protects Downstream Electrical Components: — A properly functioning voltage regulator shields sensitive controls, igniters, and motor circuits from damaging voltage spikes or drops that can cause cascading failures.
- Electrical Safety Assurance: — Using the correct OEM-spec regulator helps prevent uncontrolled voltage conditions that can pose fire or electrical hazard risks in fuel-burning heating equipment.
- Genuine Wacker Neuson Part: — Sourced directly from Wacker Neuson, part number 5200011732 carries the same quality standard as the component installed at the factory.
A voltage regulator controls and stabilizes the electrical output produced by the heater's generator or charging circuit, ensuring that all onboard electrical components receive a consistent, safe voltage level during operation. Without a functioning regulator, voltage can spike or fluctuate unpredictably, causing damage to control boards, igniters, motors, and other sensitive parts — and potentially triggering safety shutdowns or electrical faults. Replacing a failed or degraded voltage regulator promptly restores stable electrical performance and protects the rest of the machine's electrical system from secondary damage.
