Am missing Part # X42 & X42A (1/8" & 1/16" washers) - I could use ones from the hardware store right?
Also I managed to over tighten one of the magnet fixing bolts and broke it. Ugh. Coop is my friend.
OK. Still don't know how I'm gonna figure out if it makes electricity unless I hook it up to a real wheel. Maybe my Phillips.
NOTE: This is the page I'm referring to when naming parts numbers:

Ok, I have two dynohubs, one from 72 and one from 74. One is from a Supurbe and is spaced at 90mm. the other from a Sprite and spaced at 100 mm. The differrence is that the 90 mm hub doesn't have the washers corresponding to 42 and 42 A and the 10 mm hub does. So, depends on the fork whether you need them or not.
As for the "Spacing cup," you need that. The hub will not work without it. I can't tell for sure from the photos of your hub as bought, but I'm guessing that it's on there. The spacing cup goes on the generator side of the hub and fits between the spacing washers (if present) and the magnet cover plate. If you don't have the spacers, it's between the "cone lock nut" and the magnetic cover plate. Force applied to the magnet cover plate by the cone lock nut through the spacing cup is what prevents the magnetic cover plate from rotating with the wheel. It fixes the stationary part of the dyno to the axle. So, if there was a part between the dyno side locknut and the dyno cover plate that's about 10 mm thick and which has two different sized holes, a small on the outside and a big on the inside, that's it. If you don't have it, you have to figure out some way to fix the stationary part of the dyno to the axle and also properly set the OLD of your hub.
So, spacing cup (or substitute), yes. Spacers to get your desired OLD.
As for your meter, you probably have little alligator clip adapters that the straight probes will fit into. They probably came with your meter or the probes. I'm always losing mine so I end up using little alligator clip leads. You may have some of those around. If not, try Fry's. Or, if you're desperate, Radio Shack. Or, you can get everything you could possible want in your life (including groceries, coffee, etc) from Amazon.
