Measuring >10 Amps without blowing up your DMM...
...by making up a $2 shunt!

How to test high DC amperage (500+) using a DMM by making a Shunt that measures Amps as millivolts on a DMM, brilliant video explains all!

My Fluke 88v uses this simple shunt (no clamp needed) with ease to measure 600+ amps 'as millivolt' readings on my car alternator and no blown fuses...
