Or, if you are cheap, err frugal, like me you can use a burned out fuse and a multimeter. Littlefuse brand blade fuses have exposed contacts at the exposed head of the fuse that you can get at with needle probes. Or if you like, trim away more of the plastic at that end and solder on some leads. Both work well enough for occasional use.
