- Old Jeeps came with generators to charge their batteries, but new Jeeps come with alternators. On this episode I'll swap out the old generator with an alternator and super easy install brackets so my wiring and charging system are cleaner and ready to go wheeling.

Great. Now I have no reason to not convert my ‘63 AMC 232 L6 to an alternator. Damn you, Fred.
Look up at my post...it's not hard to wire a 3 wire Alt...
Dont explain yourself. No need, we are here to watch you do your thing bud!
Looks like the alternator is a Delco 10Si of some sort. I think most use up to 63a since there are people still wanting to use the Amp gauge. I wholeheartedly agree to going with parts available from a local Auto Parts store when possible. In my case, I removed the 24V generator which is a beast and got a 100a Delco. I did the TLC high-torque starter since I had to replace the 24v starter too.
I am a pro, but i really like the fact that you are getting some new people interested in car/jeep work! remember the new jeep with the bad module under the hood? would like more of that stuff... or common jeep problems=rescues
I try to balance the new and old stuff. expensive stuff and cheap stuff. thanks for the input
Ok,why an alternator instead of a generator. Generators make DC current to charge your battery and run the accessories. Alternators create AC current and convert that to DC, via rectifiers, to charge your battery and run the accessories. So why switch? Generators are bigger and heavyer than alternators. They also reach their peak power at higher RPM. As cars got more complicated with bigger and better accessories generators became larger and heavyer. An alternator will be lighter smaller and produce their max output at a lower RPM. Imagine trying to power engine, AC, radeo, and large lights all while in stop and go traffic with a generator. It would be three times as large as an alternator, run hotter and have to rev at a higher RPM than the alternator. If you didn't keep the RPM up your battery would go dead...
Thanks Mike! I'm not sure if you are agreeing with me, disagreeing with me, telling me I got it right, or telling me I got it wrong, but I appreciate the input either way...
As I understand it, a generator produces different voltage depending on the RPM at which it's spinning, while an alternator always produces the same voltage regardless of RPM.
@4xFredWilliams Fred..to Did Good...is what he is saying..I think..lol 😂
Solid state diodes made the alternator a no-brainer. Electronic internal regulator even better, although that's usually the first thing that fails.
Very nice adapter brackets. I make my own and they look it. More points off at Pebble Beach.
Correct. Generators make DC current. Alternators make AC current and convert it to DC.
Ps..a 70's GM Alt will replace that one if it takes a dump on the trail..just jump the wire closest to the Main Charge Wire with a butt connector..3" of wire...and a Eye hole connector to the main Charge wire..and keep the Wheels Down and injoy the rest of You Day on the Trail...
My '70 CJ5 had an F 134 that came with a generator. Had a second belt that drove the smog pump too.
I converted my 1952 Ford tractor to 12 volts and I have a one wire alternator. It takes high rpm to start charging, but then it will charge at low rpm. My lights actually light up the area in front of it like it should.
Awesome Fred.. I have a 51 M37 my boys' n I are working on and has no generator so found a 24v alternator to add when we get this beast running
Another great video for us guys restoring jeeps in our garages who are not super technical. Thanks so much Fred. Please keep these "How-To" restoration videos coming.
Nice kit. Saves fabing new brackets!!
That was very interesting Fred. I am not an electrical engineer either but I understood this mod! Keep the Flat fender videos coming. I will own one soon I hope.
Great video! I think I'm as excited as you are to see this Jeep back on the trail. It also motivates me to keep chipping away at my 1974 CJ5 project. Keep up the good work!
The alternator is a 10si alternator. The only things that might be different vs a standard GM 10si alternator is the voltage regulator and possibly the windings. You can get parts for it anywhere.
Good call...I would of done the same. A guy with a business that solves the problem and great quality.
The alt is a Delco 10si casing with different internal parts 10si were 37A 45A 56A 63A and some 72A. By the way love your hat.
What a great upgrade! I count on my fingers too…🤣
Great show!
Great video, Fred. I would be changing out that little wire on the ALT. There is no way that wire is going to hold 74 amps
One big problem with generators was they didn't charge or didn't charge much at idle.
Back in the early 1960's, Chrysler put alternators on their vehicles in 1961, GM and Ford by 1963.
I used to rebuild generators, starters and alternators in the 1960's at my Dad's repair shop back then. His specialty was electrical repair and carburetors which I learned from him. He also did a lot of general repair.
A lot of 60's cars had "GEN" lights and no volt or amp meters. At a low 500 RPM a lot of these lights came on and didn't go out until 1000 or more RPM's. Alternators solved that problem and as compact as some alternators were, I saw early ones capable of putting out 55 amps at about 1500 RPM. To do that with a generator you'd need a generator twice the size that Fred was showing there. There's more to this comparison and story, but not enough room here to explain it all.
You'll appreciate that alternator when driving at night on and off road Fred, especially if extra lights and other electrical loads are added to the Jeep.
Love the videos. Thank for making them. I love the flat fender and would love some more of the Dirty 80!!!
Simple is good!
Just one wire! That is amazing!
I love walking into a modern part store and asking for a 10S. Or a rebuild kit for one.
Fred check out Kaiser car head , the Super Sonic. Gives compression boost . (little bump)
generators create dc current. alternators create ac current that is rectified to dc.(sorry made this comment before reading a comment below. that has better detail.)
I converted my 400M in my 79 Bronco to a single wire alternator.
My guess is the very small pulley is the main thing that helps it run at lower RPM and not going to big on the Amps will help limit belt slip with the limited belt angles reducing wrap/contact. As you say the guy's spent a bit of time R&Ding a nice balanced system.
That’s exactly what kind of power electric vehicles use !!!
Alternator vs generator is always a hard one!
Fred what happened to the old diesel pressure washer you had. I was looking forward to seeing that old beast!
the blower motor died and I have not found a replacement yet. kinda bummed bc its such a great pressure washer.
but this little honda guy works good too
@4xFredWilliams Yeah I have the same Honda pressure washer and it has never let me down, but that HOT diesel one you have is the GOAT for sure. Nothing like HOT water for cutting through all the grease. Love the videos.
Hit the alternator with some OD green paint or the stuff you have on hand that got used on the bumper repair and that alternator will blend right in.
if it runs on batteries its going to be DC, so EV's are all DC just running crazy high voltage, like 400v or more. The AC thing from spinny winnies is because its a matter of reversing polarity of magnets, and doing so creates AC current. Rectifier reverses the - side to + via magic pixie wrangling... where as the commutator does it mechanically with large lumps of copper.
i'd be concerned about the size of the wire. it doesn't look anywhere near big enough for 75amps 12v dc even if it is just barely adequate most of the time there's no drawback to using a larger gauge wire.
How much for that old generator? They are hard to find and pricey.
First 💪🏻
you can't just log on to get the first comment and not watch the video Little T! you have to dive in and enjoy the content and end the video by going to facebook marketplace and looking for a flatfender. sorry that's the rule
@@4xFredWilliams that is a good rule!
@@4xFredWilliams I don’t like rules. 🙄 sorrrryy.
subbed and belled, switched to an AGM battery on an old 85 toyota, do i need to do anything to the alt to set a higher voltage cutoff?
What do you suggest?
Looks good, any plans to swap water pump before reassembling?
I was thinking about that too. I wish I had some free time so I could run out to California & dive right in to do that water pump & anything else that you would be willing to let a grease monkey do. 😀
It can’t be PCP power, electric vehicles can’t get wet
