Quick alternator question

[Mr. Man]

I picked up a remanufactered stock alternator today as a spare and was wondering if the pulley that comes with it is the same as the OEM back in 2004 that has the clutch. How can you tell as they look the same visually, at least to my untrained eye. Also on a quick side note the white pluginski has 3 pins is that correct. I had the dealer double then triple check the part number for the 4G regulator but Ford is so busy relabeling parts that "should" fit I'm just checking.

Thanks,:)

Picked up a new idler pulley and tensioner also.

The fact that the pluginski is white indicates it is the correct one. They also come in grey or black, both of which are the wrong type.
As to the pulley, I'm not sure if you're asking how to identify a functioning clutch pulley in general, or if you're looking to get the exact same clutch pulley as provided in 2004 (i.e. NOS). If the former, you can simply grab the pulley and try to spin the rotor in both directions - you should be able to build momentum in one direction, and trying to reverse the rotation should result in the clutch slipping. If it does that, then it's a working clutch pulley. But, if it doesn't slip in one direction, then it's either not a clutch pulley at all or it's a clutch pulley that's seized (a standard, non-clutch pulley is held in place with a large nut, whereas a clutch pulley is itself threaded, and is not held on with a nut)

If there is a cover on the new pulley then it's a clutch pulley.

Based on your info it's a clutch pulley. Thanks guys.
