good call on the harbor freight unit. i use a fluke 88 for all my other stuff, but as Ill use the clamp much less often than that, i cant quite see the 381...

fluke imo although their recent corporate bullshit selling the company and making the products shittier makes me upset

they have a dc clamp for something like $100-150 and its the same one i have. seems pretty accurate

i can pretty much tell you what large case gm alts will make aftermarket vs oem because ive clamped them

a standard ad244 large case from a junkyard will do about 115a hot at idle. a large case singer/dc power/etc alternator without hairpin windings but with upgraded parts will do about 200-220a at idle hot with some doing around 180a if the vehicle has a lower idle rpm
