Okay okay you guys are overwhelming me with infor. The heavy equipment alternators, the smaller case ones, are they comparable in size to the delco alternators? Do they have tags that detail how much amps they put out? How many amps do they normally put out at idle? I was originally going to get the newer delco alternator or use my older alternator out of my 78 cj7 and beef it up with one of the summit kits. One more question are rebuild kits readily available for the heavy duty alternators (in case I find a scrap on that needs a kit).
