My alternator went out a few months ago and I am finally getting ready to get working on it. I have researched the differences in 80 and 90 amp alternators for the 3fe and can't find a clear method for Identifying the difference. One post says the 80 amp has an external fan and I have read elsewhere that the large threaded stud is on the side of the 90 amp. I am skeptical that I do in fact have the 90 amp, although it looks like I might. So, can anyone help me figure out which alternator I actually have?
**update** - it was an 80 amp with all the characteristics of a 90 amp. I bought and modded an actual 90 amp to fit, details in post 10 **
