MPA Electrical 101-27102 Alternator

Overview

This MPA Electrical alternator, part number 101-27102, is a new charging-system replacement for heavy-duty Chevrolet and GMC applications. It is listed for 12V systems with 100A output and IR/EF 27SI/200 DR air brake configurations, making it a fitment-focused option for commercial trucks that need the correct electrical match.

Use part number 101-27102 when you need a direct alternator replacement for supported Chevrolet and GMC medium- and heavy-duty platforms. The fitment data covers multiple C, P, B, and Brigadier applications across the 1979-1991 model years.

Key Features

• New alternator assembly for charging-system service
• 12V, 100A output specification
• IR/EF 27SI/200 DR air brake application notes
• Fitment listed for Chevrolet and GMC commercial truck platforms
• Part number 101-27102 for application matching

Detailed Description

MPA Electrical 101-27102 is built for vehicles that use a 12-volt, 100-amp alternator in the specified IR/EF 27SI/200 DR air brake setup. The fitment list includes Chevrolet C50, C60, C70, P60, S7, and B60 applications, along with GMC C5000, C6000, C7000, P6000, B6000, and Brigadier models. For buyers searching for a Chevrolet C60 alternator or GMC C7000 alternator, this part number helps narrow the match to the correct charging-system configuration.

Because alternator fitment on commercial trucks depends on electrical output and mounting/application details, verify the notes against the existing unit before ordering. Part number 101-27102 is also useful when cross-checking replacement needs on older Chevrolet and GMC medium-duty trucks with the same 12V 100A specification.

What It Helps Solve

• Charging-system failure from a worn or non-functioning alternator
• Low battery charging caused by insufficient alternator output
• Electrical system instability in 12V commercial truck applications
• Replacement needs for the specified IR/EF 27SI/200 DR air brake setup
• Part-matching issues when the original alternator number is unavailable

Installation Notes

Confirm the vehicle’s year, make, model, and alternator specification before installation. Match the 12V, 100A rating and the application notes in the fitment table to the existing unit. On commercial truck charging systems, connector style, mounting arrangement, and application code should be checked against the removed alternator before final installation.

Quality Assurance

MPA Electrical lists this as a new replacement alternator, and the application data is organized around specific commercial-truck fitment details. Part number 101-27102 should be matched carefully to the vehicle’s charging-system requirements for accurate replacement selection.
