I currently have 3 motorola alternators.  
A12NAM552
A12NAM553
Tag is Unreadable

At this point (50 yrs of rebuilds), I dont trust the tag on any of them. 

I assume the 55 in the part number is 55Amps?

I see in the parts catalog that the 45 and 55 Amp have different:

4 - Isolation Diodes
14 - Diode Positive
15 - Diode Negative
16 - Stator
19 - Rotor

I dont see any identifiying marks on anyting  but the Diodes (25 and 35)

I would like to confirm that I have a 50A, 55 Amp Alternator and/or build a 60A alternator if possible.

I see that Galvins has some components availalbe for a rebuild/upgrade.

Is there any way to identify the application for the parts below that are suitable for a 50A, 55A or 60A:
4 - Isolation Diodes
14 - Diode Positive
15 - Diode Negative
16 - Stator
19 - Rotor

Will installing the 50A stator do any harm/good?

Thanks

Billd here on the forum rebuilds-restores alternators and does a very through job of it.  He would be the one to talk to to get correct answers to your questions.
