1969 Swinger 340 distributor questions

George, a point dist. uses a single resistor, not the dual resistor that the electronic uses. it's likely that your alternator was upgraded as well. was there an electronic voltage regulator on it as well? Doug

Well, me not knowing what an electronic voltage regulator looks like, I have to provide a description and hope you can answer that question yourself.

There was a blue, square unit with a single red wire coming out of the back of it, with a stud/nut on the front. The printed number on this box is P-3690732. (It was in a box like the rest of the car when I bought it.) This blue box is about half the size of a pack of cigarettes.
Is that an electronic voltage regulator?

The alternator number is 4111973. I have no idea what it is for, but it's a remanufactured generic parts store unit.

Thanks for the help!!!

George
