If the points are closed when the switch is flipped on, then the coil will be energized like an electromagnet until the points open again during starting, Full discharge seems to be excessive since the current draw isn't all that high with the coil. There may also be a problem with the ballast resistor.

You may get more answers on the early V8 part of the forum.
