i got a one wire alt. when i bought my car, the guy said it came with the motor he bought and put in the car, but he didnt install due to lack of knowledge. just wondering what numbers and were do i need to pull to find what kind it is, its a motorcraft and its big and heavy, any help would be great thanks guys

 

looked at it and can only find the number 3 on the back side, looked at the alt. bracket that came with the old motor and its been fabed for the alt to fit, is this a 3g or something

 

post a pic of it, most likely it's a truck alternator???

 

i still havnt got the connector to put pics from my camara to the computer but i found this pic and it looks just like it and i put on there were it has the number 3 and were it says moto is were it says motorcraft

 

srry computers messing up

 

*bump

 

it looks kinda like a 3g alt, hard to tell without seeing the fron't view

 

i dont have it in front of me but its real similar to this

 

how can you be for sure, does the 3g not have the fan fins or does the truck alt. not have them as well
