Come along as I walk through how I converted Lula, a 1952 Chevy Styleline, from a 12 volt externally-regulated alternator to an internally-regulated one.

That must be the snow we got too. About 7 inches for us. Thanks for the tips and advice, Richard! π

Cool video Richard! I did not think of the light bulb I thought you could just run it to the ignition side of the switch.Thanks

Your meter looks to be the same vintage as the car Richard lol. Seriously though, thanks for sharing this information. It is quite helpful.ππ¨π¦

I've actually seen SI alts with the same shaped connector as the non Si units, only facing upward like you'd expect, instead of out the backside. 3 terminals on an SI, stamped "BAT" "1" AND "2."
BAT is the big one with a nut on the back. Goes to battery hot, preferably away from the battery terminal, due to corrosion issues. at a minimum, coat connections with vaseline AFTER tightening. "1" goes to the "idiot " light in the dash (optional, just keeps you informed). "2" goes ideally to ignition hot, but yeah, you can just connect it to the BAT terminal. Thing is, the alt will be energized constantly, even with the key in the off position. If you let your car sit for several days, it can flatten a bad or marginal battery. Ignition hot is preferable, but "you do you."

10 gauge wire works if you are using a weak standard alternator putting out 45 amps or so. I run a 90 amp alternator so I upped the wire gauge to 6 gauge which is kind of over kill, I also run a inline 120 amp fuse. Part of it has to do with battery placement, the longer the wire run the heavier gauge the wire should be. This serves two purposes the wire runs cooler and you have less voltage loss.

Hello Richard really helpful video! Im trying to do the same thing, one question regarding the light bulb. Is it a special light or is it one i can buy at autozone like a 194mini bulb?
