I can tell you when the side post ballast bypass switch comes in handy with an AD converted to 12 volts with a 6 volt starter. It is when your points are approaching the moment when they should be dressed up and you haven't had time to do it because your wife is on your a** for not cutting the grass, even though it doesn't really need it, and what about the mold on the house, and the downstairs bathroom is a mess...
What was the question again?
