My voltage gauge is not working. Is my wires hooked up right on my generator?

The meter in Model A is an amp meter which shows the direction of current flow from the generator to the battery when a positive reading is seen, or a negative reading when the battery is supplying more current than the generator is putting out. Your connections look correct.
 
Turn on the lights and see if it goes toward discharge. The reproduction amp meters are not too well made. The originals work very well but they can wear out. Generators can wear out too. Batteries will go bad if they set too long.
 
I would first check the adjustment of the adjustable third brush in the generator . Push down on the aDJUSTABLE brush to increase charge rate . raise the adjustable brush to decrease charge rate .. If the adjustable brush is raised all the way up , it could be the problem . Charge rate is adjustable on the model A generators .
 
What is meant by the ammeter not working ?

Turn on the lights, does it show a discharge ? If it does its working.

If you loosen the fam belt and feed power to the generator it should run like a motor very slowly. Thats a fairly good indicator that the generator is good. If your cut-out is an original type the generator output is constant if the engine is running fast enough.
So with the engine running the ammeter should show a charge if the engine is running at a fast idle speed. As Purdy mentioned the third brush is adjustable and accessed by removing the rear band. If the generator does motor when powered but not show a charge on the ammeter then either the cut-out is bad or maybe the system just needs to be polarized. To do that just touch a jumper wire across the 2 cut-out terminals for a nano-second and let us know what happens.
