Product Details

BBB Industries N7861-7 is a new alternator for vehicles that require a CS130 configuration with a conventional pulley and external fan. The unit uses air cooling, a 2-5/16 inch outside pulley diameter, and a serpentine belt drive layout. These specifications matter when replacing a worn charging unit on GM trucks and SUVs, especially where plug position and pulley style must match the original setup. This part cross-references FTE 1101629 for the same application.

Common Problems This Alternator Can Address

• Battery warning light caused by weak charging output
• Low system voltage during idle or accessory use
• Dim headlights or unstable electrical performance
• Charging failure from worn internal components
• Noise or belt-related issues tied to a failing alternator pulley assembly
