Klein is a very well respected manufacturer of tools for electricians, and this multimeter certainly seems to have the capabilities that would apply to work on Model As. I’ve found that it’s often handy, if not essential, to have leads with alligator clips on them so you don’t have to juggle two leads and the meter while squeezing into awkward spaces. Clip leads are readily available separately, for example Klein 69410.

Having said that, almost any multimeter will do you fine. Harbor Fright had an el-cheapo that they used to give away free with any other purchase, I carry one of those in each car.

The most important thing is knowing how to properly use the meter and interpret the results. Like, don’t put your probes across a voltage when the meter is set to resistance…
