Older models (generally pre-1980s): The voltage regulator was typically a separate component, often mounted on the firewall or near the alternator itself.
Newer models (generally 1980s and later): The voltage regulator is integrated *inside* the alternator. There's no separate external component.
To find it on your specific Chevy 3500 van, you need to know the year. Then you can:
* Consult your owner's manual: This is the best place to start. It will have a diagram showing the location of major components.
* Use a repair manual specific to your year and model: A Haynes or Chilton manual will give you detailed diagrams and instructions.
* Search online for diagrams: Search "[your year] Chevy 3500 van alternator location" or "[your year] Chevy 3500 van electrical diagram". Pay attention to the alternator's location, as the integrated regulator will be within it.
Remember to disconnect the battery's negative terminal before working on any electrical components.
