Dodge Cummins Alternator Wiring Diagram
The alternator on Dodge Ram Cummins turbo diesel trucks is an essential part of the vehicle’s electrical system. Here’s a quick rundown:
- Converts mechanical energy from the engine into electrical energy
- Charges the battery(ies) while engine is running
- Powers all electronics when engine is on (lights, stereo, accessories, etc.)
- Typically mounted on the front of the engine with a belt-driven pulley system
- Contains key components like the rotor, stator, diodes, regulator and more
When choosing a new or replacement alternator, it’s crucial to select the proper one for your truck’s engine and year. Factors like output and pulley size must match.

How to Read Alternator Wiring Diagrams
Before jumping into a specific diagram, here is a quick guide on how to read any alternator wiring schematic:
- Wires are shown as lines between components
- Solid lines represent wire connections, while dashed lines show component mounting locations
- Different line styles and weights indicate different wire gauges
- Tracing a line shows the electrical flow path
- Red + signs indicate connections to positive voltage
- Ground connections show where current flows back to battery negative
Standard symbols represent generic components, while labelled parts are vehicle-specific. Having a key for abbreviations is also helpful.
