I Have done it with a scope so if your PC gadget looks like a scope it
will work (high impedence A/D converter). You should be able to see a
bad diode pair but sunce they are sold as a set I am not sure it is
much more than gee whiz info. If you have the alternator apart it is
not that hard to check them with a meter.
