    Not a Mustang - but close

    I have a neighbor across the street who has a nice 1963 Falcon. Last year, he had some electrical issues and he removed his generator and took it to a very reputable electric shop to have it rebuilt. They did the deed and he installed it and it ops checked okay.
    He drove it to a local show last weekend and the generator light came on dim, then it came on pretty bright. He was able to drive it home (4 miles) okay, but he is wondering what the problem might be. I told him that the voltage regulator was probably bad, as he did not swap it when he changed the generator.
    I haven't worked on a car with a generator in a month of Sundays. Do you still have to flash the field to get it to work or what?

    Me too, Ron, but as the old crainium rememberizes, you do need to polarize (flash) the field on gnerators when changing the regulator.  Only problem is, Ford and GM used a slightly different procedure and I can't remember either one.  Chrysler used same as Ford (Autolite) I think but they went to alternators in the early 60's, just about the time I started doing  automotive electrical work.

    The 'light' indicates the generator output voltage is less than the battery.  The brighter the light the means the battery voltage is decreasing.  I suggest taking both the generator and voltage regulator to the shop and have it checked out ... if they can.  I'm not how many rebuild shops they are today that can troubleshoot old automotive generator systems.
    I would consider getting a genartor that is modernized with alternator internals.  PowerMaster offers them.
