Alternator amps?
1997 E350 6.8 . How can I tell what is the rated amps for this alternator? There are no visible tags or markings. A place I read says all 6.8 have 130 amp, another says could be 110 or 130. Nothing in my Ford book says.

- 95 or 130 amp
Look clsely on the coil assembly. It may have the identification inscribed on it. You may need to use some steel wool to high light it. - Get a flashlight.
Look down at the alternator
And through the ventilation holes
What color insulation is on the wires? - Scroll down to photo of 130a 3G where it explains about the number of holes in the Y compared with the 95a 3G

3Gs come in two sizes: A a 7-inch “small case” and an 8.25-inch “large case.” Both can be found in 95- and 130-amp versions. The 95-amp model is easily identifiable by three sets of four round cooling holes in the case’s ribs that make a “Y” behind the pulley. A 130-amp high-output version uses three sets of two big cooling holes in the “Y.” - I'm lazy. When I see purple wires it means the alternator is 130 amperes :) Automatically, the large case. But your way works too BFL13. But it does not zero in on the amperage of the large frame. Green wires is a lesser amperage unit.
- Op here. 2 holes in the "Y". Reddish hue on the windings. So 130?.
- I can hardly see the alternator in my MH, never mind count holes or what colour the wires in it are. I can just make out it is a 2G from what is visible. I guess you need to practically remove the engine to change the alternator, no idea. :(
- OP you have the 130 amp large case
BFL: You cannot see it from the outside but the stator insulation color of the highest amp (75) is yellow. Unless it has been changed and a "remanufactured" alternator has found it's way there, of course.
OP can you use an extendo-mirror and a flashlight and peer behind the case. Is the voltage regulator plastic case black, gray, or white? - my 97 ford 460 alternator
looks like the large case picture
can not see the front
it has (2) dark? and (1) wht wires, on a blue connector
plugged into what i think is the VR on the back of the case, the VR says motorcraft and is looks to be black, i can't make out any numbers MrWizard wrote:

It's a 130. All F53 460 chassis came with 130 amp alt.Or the previous owner could have installed the wrong alt.
