[QUOTE="maylar, post: 965361, member: 541144"] Umm... yes... it's called an ammeter (that's the correct spelling, not AMPmeter). I have one that'll measure up to 60 amps. It goes in series with the alternator wire. Anything higher than that and you'll need to build it yourself from a shunt and a millivolt meter. Current Shunts can be had from Simpson Electric: [URL="http://www.simpsonelectric.com/accind.htm"]http://www.simpsonelectric.com/accind.htm[/URL] If you had a shunt that was rated 100 mv at 100 amps, then each millivolt (.001v) would be an amp. Measure the voltage with your DMM on the lowest scale. [/QUOTE]
