Alternator Overview

This 12-volt alternator is built for charging systems that need stable output and OE-style fitment. It is a Delco-family unit with an internal regulator, external fan, and a clockwise rotation pattern for applications that match the listed configuration. Part number 7861-7R-6G is a direct reference for this charging system replacement.

  • 105-amp output for vehicles with higher electrical demand
  • Internal regulator for integrated charging control
  • 6-groove pulley with serpentine belt drive
  • Pulley included for a complete replacement assembly
  • Delco family design for listed Chevrolet and GMC applications

Fitment Details

Compatible with a wide range of Chevrolet and GMC trucks and SUVs from 1988-1994, including Chevrolet Blazer, C1500, C2500, C3500, K1500, K2500, S10, S10 Blazer, Suburban, and GMC C1500, C2500, C3500, K1500, K2500, Jimmy, Sonoma, Typhoon, Yukon, and related models. Fitment varies by amperage, plug style, AC equipment, and housing configuration, so match the notes exactly before ordering. Part number 7861-7R-6G is used across multiple Delco 105-amp applications.

What It Helps Address

  • Low charging output from a worn alternator
  • Battery drain caused by inconsistent system voltage
  • Charging issues after electrical load increases
  • Replacement needs for Delco-style 12-volt systems
  • Fitment problems when the pulley, plug, or amperage rating does not match

Installation Notes

Verify the vehicle’s plug style, amperage requirement, belt type, and rotation direction against the fitment notes before installation. This unit uses an internal regulator and a serpentine pulley setup, so the existing charging system configuration must match. Confirm the application details for Chevrolet and GMC models listed under the fitment table to avoid ordering the wrong alternator.

Quality Assurance

Power Select alternators are engineered to deliver the amperage needed for modern electrical loads. The manufacturer states that proprietary components and processes are used to support long service life and consistent performance. This part cross-references BBB Industries (e.g., 7861-7, 7981-7) for the same application.
