The dwell meter has 2 leads, black and red. Normally the red goes to the coil terminal that leads to the distributor points and the black to ground. On the Model A I think you need to reverse the connections, ie red to ground and black to the coil. The meter should work with the 6 volt system. Mine does.

You really don’t need to set Model A points with a dwell meter. Use a feeler gauge or a dial indicator. Practice setting the points with a feeler gauge and check your work with a dial indictor to see how accurate you are. The dial indicator also gives you the added benifit of seeing if your cam is within spec. Rotate the cam and check each lobes dial reading. First make sure your points are in alignment before setting. Also make sure the point surfaces are not damaged. A slight concave rounding of the surfaces is better than flat if you need to file them. Buy a point file and a point alignment tool.
