A: Your original regulator is points type? Then likely one of the wires between the regulator and alt are broken (whichever one is the battery voltage) Had this happen on almost every Ford I've owned and many that had charging system trouble (it was one of the 2 middle wires of the flat 4 that always broke off) The electronic ones pop within minutes (sometimes seconds) when wired that way (or never even kick in), but the points type overcharge because they think battery voltage is too low.
