From the plug wire to ground, you should read several K-ohms, maybe 5 - 15 K-ohms. From the points connection to ground you should read between 0.5 and 1.5 ohms.
To test the coil, connect a spark plug from the plug wire to coil ground, connect an ignition condensor (any will do for this test) between the points terminal and coil ground. Connect the negative of a 6V battery to coil ground and touch the points terminal momentarily with the positive lead. This should give you a spark at the plug.
