The Honda 31700-ZP1-J71 Automatic Voltage Regulator Assembly is a genuine OEM component designed for ES6500 and EX5500 generators. As a direct Honda OEM part, it is manufactured to the exact specification of the original unit it replaces, ensuring the output voltage of your generator is controlled and stabilized the way Honda engineered it. Confirm your generator's serial number against the fitment table before ordering, as Honda occasionally supersedes parts at production serial breaks.
Key Features
- Genuine OEM Voltage Control — sourced directly from Honda, this assembly regulates generator output to the tolerance the alternator was designed to deliver, not an approximated aftermarket equivalent
- Direct OEM Replacement — engineered to install in place of the original unit with no adaptation, preserving the electrical integrity of the ES6500 and EX5500 generator platforms
- Fits ES6500 and EX5500 Generators — designed specifically for these Honda conventional generator models; verify your serial number against the compatibility table to confirm the correct assembly for your unit
- Restores Stable Power Output — a failed or degraded voltage regulator causes fluctuating or out-of-spec output voltage, which can damage connected equipment; replacing it brings output back within the correct range
The Automatic Voltage Regulator Assembly is the component responsible for maintaining steady AC output voltage on a conventional generator. It monitors the alternator's output and automatically adjusts the field current to compensate for changes in load, keeping the voltage delivered to connected tools and equipment within a consistent range. When this assembly fails, output voltage becomes unstable or incorrect, which can cause lights to flicker, motors to run poorly, or sensitive equipment to shut down or sustain damage.
