A '49 would indicate a front mount distributor, that is more important to know than a model year or a serial number. So, using JMOR's fine document on wiring, find your setup and follow it to a T -no shortcuts allowed. Do you have the Ballast Resistor? Is the Voltage Regulator still in the circuit? It shouldn't be if using 12V. There is no voltage adjustment. You set up the system for whatever you are using (6V/POS GRN or 12V/NEG GRN)and that's it. With a 6V Coil you need to add an inline ceramic 1-OHM resistor. Best to buy a 12V coil and do away with the external resistor altogether.
