The 250 amp Ford Motorcraft type 6G series high amp alternator requires a Quicktifier Remote Bridge Rectifier because the output is to great for a single bridge rectifier. Please make a Quicktifier selection when ordering your high amp 6G series alternator. If you order a 6G series alternator at over 200 amps without a second set of diodes, it will fail more quickly , 6G series bridge rectifiers are not heavy duty enough to handle the excessive amperage alone .

Whenever possible it is best to upgrade from the Small Case 6G series Alternator to the Large Case unit. The Large Case Alternator gives you more power at idle, absorbs and dissipates heat better and will last longer at higher amperages. The Large Case Units bolt directly in place of the small case and the plug is the same. F Series, E Series, Excursions, Explorer and Expeditions and Mercury Mountaineer with the power Stroke Diesel Motor Many Ford trucks came standard with the Small Case alternator and can be upgraded to the Large Case unit or better performance.

Large Case 6G Series Alternator vs Small Case

The Challenge: In 1999, Ford Motor Company transitioned from the robust large-case 3G alternator to a smaller, 110-amp 6G series alternator for their 7.3L Power Stroke Diesel engines. This change left Power Stroke owners with limited options for increasing their charging capacity. While dual alternators and upgraded small-case alternators exist, they come with drawbacks such as increased complexity, reduced reliability, and limited low-RPM performance.

The Solution: Our large-case 6G alternator upgrade offers a superior alternative. It provides the power you need without compromising on reliability or ease of installation. Experience enhanced output at all engine speeds, ensuring your electrical system can handle even the most demanding accessories. Installation is straightforward, utilizing the same mounting points, belt, and plug as the original alternator, eliminating the need for any modifications.

Benefits:

  • Increased power output: Enjoy ample power to run all your accessories and equipment, even at idle.
  • Improved reliability: Our large-case alternators are built to last, reducing the risk of unexpected breakdowns.
  • Easy installation: No special tools or modifications required; it's a direct replacement for your existing alternator.
  • Peace of mind: Rest assured that your truck's electrical system is up to the task, no matter how demanding your needs.
