I know this has beatin to death but I’m in the process of doing the 6-12VDC conversion, after doing a lot of reading I’m still not confident in this conversion. I’m looking at this kit https://www.vintageautogarage.com/19...p/pgf4953k.htm
im assuming this is a 1 wire alternator, couple things I’m confused with. I don’t see how the voltage would be cut to the battery to prevent over charge. Once I get into the project I’ll post back because I’m also not sure about the 12 to 6V gauge reducer.
Whats you’re guys thoughts on this kit, seems expensive.
That says it is for 49-53 flatheads, which I would interpret to mean it is for Cars, not trucks. The alternator mounting position is about 1/2" different between the two, so I would clarify with them if it is for Trucks.
That is a complete changeover kit, with electronic ignition and a bunch of other stuff. They also sell just the alternator kit for almost $300 less.
I have an externally regulated Ford alternator I thought about using instead of the generator. I bought a wide belt pulley for it. I would still be able to keep the wiring pretty much the same. I have a solid state regulator that would just bolt in place of the old style. I like the look of the Ford or MOPAR alternators better than the GM. Anyway, that was my backup plan.
Unless you just have to have an alternator that looks like a generator, there's no point in spending $400+ on that unit when a standard alternator can be had for less than $100 and work perfectly fine. My 2c.
Personally, I don't see the big deal of a 1 wire alternator. Is running an additional wire or two actually a deal breaker? They can all be bundled together nice and tidy to keep the engine compartment just as clean.

An internally-regulated GM alternator that is not a 1-wire needs a light in the Field circuit. Some people don't want to have to drill their dash for that. As many questions as I see on "how to wire my 1-wire", I think a lot of people find the extra wiring too much of a challenge. And if 1-wires work, why not simplify?

Thanks, Ross. I was thinking there are compromises necessary when going from 3 to 1 wires from the alternator. The loss of a warning lamp was one, but I suppose that only applies or matters to applications that use a gen or alt lamp in the dash. Without going back through a bunch of reading, I don't recall off the top of my head anymore what else one loses. So yes, I would agree, whatever works, great. I guess my point was it seems like everyone feels the need to switch out whatever they have and go with a GM one wire alternator, and that may not necessarily be the best option, depending on the application.
The indicator light is not absolutely necessary as long as you have other means of monitoring the charging rate such as a voltmeter or ammeter. I really don't see why this is a challenge.
