Gary Lewis Posted August 3, 2023 Share Posted August 3, 2023 Well, so far so good. It seems to put out a little less volts than my old alternator, the voltmeter hovers around 13 with the new one. With the old one, it was a little over 13. I imagine that is a function of the regulator. I haven't driven the truck a whole lot, but with the fans on and headlights and wipers, and AC, it won't drag it down much on the voltmeter. The old alternator would drop to about 11v. Part of the new alternators output capabilities come from this, no doubt: When I saw that, I had to wonder if the belt was going to be short enough. It is, but there's a lot less room on the tensioner than there previously was. I will have to watch for belt slip as the belt ages and stretches. Wow! I wouldn't have thought that they'd send that much smaller of a pulley, but they obviously did. That may account for the extra output at low R's. And yes, the voltage difference is due to the regulator. There are several different settings, and some of them have voltage reductions based on temp. But glad it is working!
