Thanks for the accolades, your install looks good. The unit you have from me is rated at 24V (28v) and 130A with 200F under-hood cooling air temps. It actually spit out 177 amps on my tester before I shipped it out to you. I test everything before I ship out. It has twin internal fans, includes 8 rib serp pulley, and the internal voltage regulator is not an adjustable potentiometer (thank goodness). Instead, it is temperature compensated, so it will automatically set a slightly higher charge and system voltage in the winter, and slightly lower in the summer, as in the winter one can expect longer cranking and a desire to push more energy back into the battery quickly, batteries will not out-gas as easily in colder temps so they can handle a bump in recharge voltage. You won't have to study the voltmeter anymore, these are close the hood and drive pieces, same as what is used on todays vehicles, not that of 40 years ago like what it replaced. These are not low cost, because they are genuine, new, and not reman or $100 Chinese clones, plus they are more than double the output capacity of what it replaced. At 28V and 130A, it is a 3640W generator head, and even more when cold at first start up. Also nice to be about half the length, allows more room under hood to work. Sorry you had to buy the bracket at full price, but you did it right and should never have to look at it again. These work even left outside when pushed into the junkyard ground and full of mud, as we have designed and tested them to do so. I added one on a scissor lift I have, it has lived outdoors uncovered for over 15 years now, and it works same as the day it was new. I have never touched it, it is heavily oxidized on the outside, and it spits out great power. Because of this, like ss55 said above, I have not even had to replace the battery on it in 10 years also, still works perfect, cranks right up even in 10F January temps. Correct NHC-250 and 8.3 bracket p/n's from Cummins are published in other threads, I am considering to combine all info into one. The above alternator will not over-volt if improper shut-down sequence occurs, which is also an added bonus to protect the ABS and PCB modules. PM for price if you are done pouring money and worries into your stock one.
