Description

Nothing’s more frustrating than a charging system that won’t behave. One day your lights are bright, the next they’re dim, and pretty soon you’re wondering if your battery is good or if the alternator is the problem. This external voltage regulator brings order to the chaos by controlling exactly how much power your alternator sends to the battery, keeping everything in the sweet spot your electrical system needs.

What You’re Getting

  • 28mm mounting size fits the original regulator location perfectly
  • Precise voltage control prevents overcharging that damages batteries and electrical components
  • Weather-resistant housing handles dust, moisture, and temperature swings
  • Direct replacement design means no wiring modifications or adapters needed

Built for Real Farm Work

This regulator keeps your tractor’s electrical system running smoothly by controlling the charging output from your generator or alternator. Whether you’re running long hours during planting season, working into the evening with lights on during harvest, or using hydraulic implements that draw extra electrical power, this regulator maintains steady voltage output so everything runs reliably.

Made to Last

Farm equipment electrical systems take a beating from vibration, dust, moisture, and temperature extremes. This regulator is designed to handle those tough conditions without failing when you’re counting on it. The solid-state design means fewer moving parts to wear out, and the weather-resistant construction keeps moisture and dirt from causing problems.

Installation Notes

Before installing, make sure your tractor’s electrical system is 12-volt negative ground. Always disconnect the battery before working on electrical components, and double-check your wiring connections before reconnecting power. Mount it where the original regulator lived—the 28mm size ensures it’ll fit right into the existing bracket.
