I have built an AC induction generator. The only diode I have I took off of an old computer, but I used my multimeter's diode test, so I'm pretty sure that it still works fine. I want to be able to connect a DC ammeter (with needle, not digital) to the generator (if I connect it just plainly to receive AC it doesn't work, as expected). I think I should just be able to connect the diode in series with the generator and the ammeter, but the needle doesn't move still. The generator doesn't produce too much current, but it should definitely be enough to move the needle a little at least. The diode couldn't be backwards, right? I've also tried using several other diodes and LEDs (new, from school) and they don't provide any better results. They all seem to block all current from going through. Also, it seems that when I measure the voltage across a lone diode (not connected to anything), it has a voltage like it were a capacitor or something (it isn't). Any help is appreciated.
