How to measure amp alternator output?

[tyronekndrck 10+ year member]

I bought a 240 amp alternator few months ago and can tell it keeps up with my system way better than my stock. But I'm curious if it's really putting out said amps. No matter what shop I call they all end up telling how to check the volts and not the amps. I already know how to do that. What device is needed to measure the amps output

You need a dc clamp meter

Something like this DC Clamp Meter

Thanks guess I'll have to buy one since most of these shops around me don't have these, or even know the difference between amps and volts

they just don't care, not a lot of shops will have a dc clamp unless they're large with high quality work, even then they probably will just say nah because it's not worth their time lol

you can get them for about $120 on amazon

Just look around craigslist. I just recently bought a 400A AC/DC clamp meter brand new in box from some crackhead for $20.

You could get a clamp add on that you connect to your dmm

I have a fluke one that on my dmm its displayed in mV but 1mV = 1A
