Speedometer can be tested using a small nail that fits into the square hole where the cable goes(file to make square, and cut the head off), and then attach a variable speed power drill and slowly power it up, should see the needle move up as speed of drill goes up. If its reversible, you can test that, and nothing should happen in reverse.

Amp meter can be tested on the bench by placing it in series with a headlight and the battery, needle should move up or down depending on which side (+/-)you have it connected to the battery, you can double the headlights to get more draw if you want the needle to move higher.
