Radio Shack 22-172 (Model 2200172, UPC 040293278861) True-RMS Digital Multimeter with high-current AC/DC clamp

There are MANY better brands & meters available, but for what it does, this one is surprisingly affordable. Particularly: True-RMS ACV & Hz, and inductive 800DCA clamp.



Since this meter has been out of production for many years, and RS has closed most of its stores; if you can't find one of these, don't be surprised. Just shop Amazon/eBay/etc. for something similar. The big inductive clamps on top aren't necessary for most automotive work, but this meter has them, and they can measure DC (most only measure AC, so look closely):



These pierce probes are expensive, but good accessories to go with any DMM:



Alternatively, common stickpins can be used; but don't allow them to short to each other, or to any other wire or grounded metal. These are cheap backprobes that can also pierce.
