How do you tell what amp alternator you have by looking at it? I have the one on the car and an extra one I was going to have rebuilt as a spare and was wondering how to tell what the amp rating was! Thanks for your help!!!
What is the casting number on the pad?
the numbers on the alternator are 3438713 5305

Are you sure it is not 3438173? I can't find a 713. This high a part number should be a 2 field alternator - '70 up but your pic is a 69. Are you running a dual field alternator?
If it is 3438173 that is a 50 amp unit....standard is 37 amp.
Yes your right! I got those two numbers backwards! Yes it has two field connections! My car is a 69 but there it's not factory stock! Thanks for the reply!
