Summary

  • Wide Compatibility: Designed for Kohler 8-25 HP engines equipped with 15 Amp alternators, this voltage regulator rectifier features three clearly marked terminals in a row-AC, B+, AC-for straightforward installation. Delivers a stable output voltage of 14.5 ±0.5V to support dependable electrical performance.
  • Extensive OEM Replacement: Replaces a broad range of OEM part numbers including 4140309, 2575503S, 4140305, 25 403 03, 25 403 03-S, 25 755 03, 25 755 03-S, 41 403 01, 41 403 03, 41 403 04, 41 403 03-S, 41 403 05, 41 403 06, 41 403 06-S, 41 403 08, 41 403 08-S, 41 403 09, 41 403 09-S, 41 403 10, 41 403 10-S.
  • Built-in Charging Protection: Includes an integrated battery charging protection circuit that continuously monitors the charge state. When the battery reaches full capacity, the regulator automatically reduces or stops charging to help prevent overcharging, minimize battery swelling or damage, and extend overall battery service life.
  • Durable Premium Construction: Built with a robust aluminum housing that resists vibrations and corrosion for long-term outdoor use. The internal heat-dissipating silicone compound efficiently transfers and disperses heat away from sensitive electronic components, improving thermal stability and helping prolong the rectifier's working life.
  • Stable Voltage Output: Engineered to maintain a consistent DC output of 14.5V ±0.5, this regulator rectifier helps protect vehicle and equipment electronics from voltage spikes, undercharging, or unstable current. Ensures reliable starting, brighter lighting, and more consistent performance for your engine-powered equipment over time.
