This is not a factory alternator. It is a "redesigned" aftermarket Ford Alternator. Below the dotted line is a cut and paste of the original ad. Read the entire ad. Every Word. Now before you peek, lo...

The output stud on my externally regulated 50/120 chrysler alternator is steel, and Not an impressive diameter by any measurement.
Yet It still can deliver 120 amps. For how long? I know not. I only have 90Ah capacity, and it can take 65 amps from grid powered charging sources for ~20 minutes when depleted 56 of those 90AH, before tapering begins at 14.7v.
Chrysler in their wisdom located the alternator a few inches from exhaust manifold. I added a heat shield between the two long ago.
I have a temp sensor on my alternator casing. Idling at max load and temps skyrocket to the 200F range fairly quickly. Low speeds and low rpms is similar. Highway speeds maxed out amperage wise, and it is rare to see over 130f.
I do assume output stud is much hotter.
I could not really make use of a more capable alternator with the battery capacity I have, and I am not seeing the need for more battery capacity either.
