What is the amperage of alternator on a 2004 F-250 6.0l diesel?

The amperage of the alternator on a 2004 Ford F-250 6.0L Powerstroke diesel varies depending on the options and specifications of the truck. There's no single definitive answer. You'll likely find either a 130-amp or a 180-amp alternator. To know for certain, you need to:

* Check your truck's sticker: Look for a sticker under the hood or inside the driver's side doorjamb that lists the alternator's specifications.

* Check the alternator itself: The amperage rating is usually stamped directly on the alternator.

* Consult a parts catalog: Use the VIN number of your truck to look up the correct alternator specifications through a parts website like FordParts.com or a similar online source.

Without access to your specific vehicle information, I can't give you a precise amperage.
