What model Packard are you working on? How are you determining TDC? Is it possible you are using the marks on the vibration damper to determine TDC in which case you may have the TDC at the exhaust stroke position for #1 cylinder? Turn the crankshaft 360 degrees to the TDC mark again and see where the distributor rotor is pointing. Remember that the crankshaft rotates twice for each time the distributor rotates. If you are indeed at TDC on the compression stroke and the rotor is not at or very near the # 1 plug wire terminal the engine will not run.
Please give us more information on your battery problem as I personally am not quite sure what the problem is that your trying to solve. In any event others on the site will be more knowledgeable than me who will be able to give more detailed advice. In any case welcome back and I hope that your problems can be solved.
