Glowing Coil Terminal

And just keep an eye on the coil.... that much heat on one terminal is not good and may have effected the long term survival of that connection.

Once you connect the choke up to the input side of the ballast, then get a voltmeter and check the voltage between the battery + terminal to that new connection point, with the car at a fast idle. If it is more than about 0.5 volts, then there is too much current being drawn by the electric choke through the ignition switch and the wiring to the ballast. At that point, either the choke connection needs to be moved yet again before the excess current burns up another connection, or the poor connections need to be corrected. You would be wise to not ignore this issue; it is potentially a sort of time bomb....
