64-72 charging system wire up using GM 3 wire internally regulated alternator

IF YOU ARE HAVING TROUBLE HOOKING THE ALTERNATOR UP I JUST UPLOADED A VIDEO EXPLAINING HOW TO DO IT, SORRY I GOT A LITTLE AHEAD OF MYSELF IN THIS VIDEO
IF CAR WONT SHUT OFF TRY PUTTING THE #1 WIRE ON ALTERNATOR TO THE ACCESSORIES ON THE KEY SWITCH...
or run #1 wire with a radio shack rectifier diode $3 at radio shack pointing towards the alt
THIS IS HOW THE ALT IS HOOKED UP TO A GM VEHICLE... ALL IM DOING IS SHOWING YOU HOW TO WIRE UP THE ALT.. YOU WILL HAVE TO FIGURE OUT WHAT IS DIFFERENT ON YOUR SET UP, BUT THIS SHOULD GIVE YOU AN IDEA ON HOW THE ALTERNATOR IS WIRED......because im assuming not everyone is putting these on ONLY GM cars now
A POINTS IGNITION OR ANY TYPE OF IGNITION COIL HAS NOTHING TO DO WITH THE ALTERNATOR HOOKUP
YOU DO HAVE A WIRE RAN OFF OF THE STARTER SOLENOID ON "I" or "R" position to the positive side of the COIL ON GM POINTS TYPE IGNITIONS THAT ARE ALL 6V...(ford may wire them opposite) .(they will use a resisted wire or WHITE ballast resistor on 12 volt systems...) but this has nothing to do with the alternator.. that is giving 12v to the coil when starting the engine.
YOU CAN SUBSTITUTE THE DUMMY LIGHT WITH A DIODE POINTING TOWARDS THE BATTERY
just an idea on how to hook a GM 3 wire internally regulated alternator up
alternator is a 79 mote carlo 305 from oreilly auto parts

[@michaelnelson9140]

For those wondering what the R terminal is on the starter solenoid ? On the older contact points ignition systems. 12v was too much voltage with the engine running. It would prematurely burn up the points. So they ran a resister to the points in the distributor.and drop the voltage to 9 or 10 volts. The R on the starter, also ran to the distributor, but only sent power during cranking. Giving you 12 v. To the points during cranking, as an aid to help start the engine. 12v.= hotter spark.once the engine has started, you let the key off the crank position, and the 9 volt resister wire was now running the distributor.

[@Buzz135]

Exactly

[@gregwbressler]

#1 alternator exciter terminal wire requires diode inline or key won't turn off engine on 10si alternator. Do not buy new alternator if dummy light does not shut off and engine does not shut off with key.

[@jackflash538]

You make an EXCELLENT teacher! Few folks would take the time to lay out an open air high visibility functonal model for others to view so they can actually "Follow The Wires"(paths) so they can fully comprehend what you are teaching them to do. Great instructional video Chris!!!

[@richardcranium5048]

Dude, I'll dance at your wedding, make no mistake about it, you are the man. I've got an 86' GMC, and the wiring on it is a mess. I've been pulling my hair out trying to get it straight. If only I had found your video yesterday morning. No lie dude, this is the best, most concise, idiot proof, no fuss no muss, instructional video I have ever seen. Much respect to you my Friend

[@billarroo1]

WOW GREAT explanation, I love it when someone understands that we're not experts, and shows us in basic understandable language 😃😃😃 Thanks

[@johnnyblanco3628]

Hey man Thank you for making this video and your 2nd video pertaining to this. I got an old 69 c10 wired ALL WRONG! they used painless wiring kits and trust me it was nothing less than PAINFUL!! This video alone allowed me to come back to thinking simply. as I am a mechanic and this puzzled me for weeks. it took a "2nd eye" for me to get collected again. Good emphasis where needed on particular gauge wiring. Thankyou

[@benmillard3755]

Big thanks here as well, helped my 12 volt conversion go much smoother since I couldn't get a single wire alternator. It was very informative and you kept it simple as it should be. Thanks again

[@andylubbe7733]

Hi Chris, this is one of the most informative videos I have seen. Very helpful thanks. Due to a faulty ignition switch I burned out the starter. On this old tractor I had to replace everything and this helped me tremendously. Great stuff !!!

[@truebetold65]

Chris..it is people like you who truly change people's lives just by your teaching.. thank you and my Yahwah bless you in Yashauwahs Holy name. Amen.

[@gza06955]

You are very generous to share your knowledge. This will definitely be a reference when I start wiring my 85 monte SS back up. (previous owner cut out most wiring for some reason.) Also have an 87 SS with a drain. Will double check the wiring on that one. Thanks again.

[@GOrdonGREENleaf]

This is the best and easiest to understand video I found to explain this. No nonsense and too the point. You're a great teacher. This helped me with my 50 CHEVY TRUCK 12V conversion. I especially appreciate the safety factors you stress, wire guages, etc. I will however add a 50 amp in line fuse to the hot wire that feeds the whole system to prevent any spikes.

[@charlesmares2550]

Thank you for your video, it helped me to understand and to rewire my 1973 Case 580 CK tractor. The alternator that was on the machine had two wires not three, but I went out and purchased a GM Three wire alternator. The prestolite alternator wasn't working so it had to go. Your video was very informative and easy to understand. Now the dummy light works. Thank you again Charles Mares

[@adrianatoscano6528]

I love though you drew it,because unfortunately not every body learns the same way and as an old woman it takes me more time to get it. I home more people in KZbin can adopt this system and help more people like me learn easy and fast. Thank you very much.

[@thorcole2089]

Big thanks for this I have a 73 pickup with a birds nest of wires that wont run because the last owner wired it all wrong so I plan to strip it down and re wire it but I dont know much about electrical stuff on cars so I wanted to be sure on the basics and you did this in a very simple but informative way that I understand! Again thank you!

[@buckdude62]

Chris, thank you very much for making these videos. I am 54 years old and grew up turning a wrench or two with my day - first car was a 1970 Grand Prix (my dad had a '69 GP). Currently I have a 1969 Grand Prix (428)- which I screwed up the charging system (don't ask how) - anyway, my father passed away several years ago, and without his guidance, I have used your videos to help me through several fixes - THANK YOU! Completely awesome! Much respect.

I like the way you present your material- you talk about the same speed that I listen.....you have a knack of simplifying things and I really appreciate that you get to the point and skip all the stupid jabber that so many other You Tubers put in their videos.

[@rtchow3000]

hey Chris, I was trying to finish connecting my 1964 scout 80 starter switch. your video helped me, clear and with precise drawing. I made a sketch to have the reference when I do this connection. deeply appreciate your help. bob

Thank you for explaining in detail , a simple way to wire my sbc ...Plus you told me what gauge wire to use..which is what I was looking for..

[@glennkrieger]

Dude, this is such a helpful video! Great explanation, great diagram, and you used real props to explain. Thank you for helping at least one person here a lot!

[@filmart430]

This was EXACTLY what I wanted to watch!!! I bought a 63 c10 and it didn’t have an ignition switch. The wires under the dash were all jacked up and spliced with different colors. Needles to say I did trust the wire colors. Thank you very much.

[@billgarris2236]

It's true what they say! Use it or lose it. Being a retired heavy equipment mechanic in my late 60s, I worked on all types of cars as a kid and did all this type of wiring work back then. Now I have to refresh the brain seels and you are a great help with that for sure. Keep up the good work.

[@radd6564]

outstanding vid, thanks for putting the time and effort into this.

[@Candyvyorn_]

Thank you man this video really explains it in a way other videos couldn’t. Really helped to see you actually wire it up outside of a vehicle. Thank you.

[@garyeads1220]

Chris, I appreciate the help very much. Drawing the diagram is key for me. I have a John Deere Diesel engine that my so-called, X mechanic rewired. He had a small clamp on one end of a wire you were required to clamp it on the positive side of the battery with the other end of the wire going to the fuel pump. We had to hook it up to start the engine and unhook it to kill the engine. I am fixing to go repair my equipment with the help from you. I subscribed to your channel and look forward to many more of your demonstrations. Now I have to get to work. Thanks again!!!!

[@MichaelmhAshley]

Thanks for making this procedure so simple to understand. Great job. Working on the wiring for a CJ 2 A(1948).

Perfect explination. Thanks man I am in the process of a complete rewireing of my 66 chevelle SS 396 using American Autowire. I ripped out the old and after doing the simple stuff I went to the engine compartment. To say its confusing is an understatement. The wires are different colors than what is normally there. Tough times...

[@markperez2438]

video was great. after watching I was able to fix a problem with my corvette that had me ready to throw in the towel. lol. and it took about an hour and cost me 10 bucks. thanks again brother. u r. the man!!

[@hartland749]

Good video man! I had replaced the starter on my old Camaro and didn't have any power after I got the new one back on.. A small wire was coming off of the battery hot wire cable that I assumed was going to the junction box. As it turned out the 12 volts to the junction block was actually coming from the starter hot wire terminal, which of course I hadn't hook back up.(to be honest I had never seen that before) I'm glad you mentioned it in the video, or else I would have looking in a whole different area. As soon as I heard you say that I knew what had happened. I'm not a great mechanic, but I understand the electronic part pretty well. Thanks for taking time to do this.I've learned a lot from your videos. David

[@chriscraft77022]

yeah, after 71 they ran a fused link off of the starter to feed everything.. good comment

[@scanner2350]

Great video and very informative. Only thing is that you should have mentioned that the big cable going from the battery to the starter is a POSITIVE cable. Given that the cable is black some people might think that it is the NEGATIVE cable going to the starter.

[@applepear187]

Best vid for me to understand how it all works. Will be completing my '89 Massey Ferg tractor. Can't wait to get started. Thanks so much pal. 😊 In the late '50's chevy Dad's car had a generator and voltage regulator. He'd turn on the headlights on long highway trips so that the regulator wouldn't overcharge the battery. Gas was 39 to 50 cents a gallon then.

[@timthemechanix]

Thanks for the refresher course. Been tied up fixing newer stuff forgot all this. Just had someone bring a truck to me, 78 Chevy, that I don't think even one wire worked. Someone replaced all the gauges in the dash with aftermarket, cut holes out where the original gauges were and literally used silicone caulk to glue them in. An amp gauge, that was tapped into the power supply to the ignition switch. The copper oil line to the gauge was cut about 5" before the gauge, a rubber hose with 2 clamps on a plastic nipple connected it to the gauge, It had been leaking oil down onto the switch. The aftermarket temp gauge with the probe into the the head had just been cut off when they exchanged engines. As for the alternator, the battery lead ran all the way back to the firewall and was butt connected directly to the #2 alternator lead on the alternator, with a big yellow splice connector barely connected to a red wire into the harness. Plus 10' of rubber gas line from the saddlebag tank switch valve laying on the exhaust to the manual pump, then a metal line up to the manifold, from the pump, that had a kink.... what a mess. And the one working tank is full of bad gas. All this crap connected to a new engine, trans, Edelbrock carb. Now new electric fuel pump, ran to original metal line along the frame. Tomorrow hopefully I can finish this mess, thanks to your help.

[@jwrhynejr.6689]

Thanks for your effort to explain wiring for this setup!

[@jamest.5001]

it wouldn't hurt to use 8 ga. wire from the alt. to batt. especially with higher amp alts. like 100 amp and up. and if long distances. or 150 amp plus 6 ga. or 4 ga. wire if using high current devices. more wire. means less voltage drop. and more current flow. and don't forget the ground. or negative side. there has to be a ground strap or wire. from the batt. to the engine. and body. I have heard of fires from poor grounds melting break lines . and fuel lines. because of the metal lines carrying the full current of the battery . when starting. or under heavy load. lots of the time ppl forget about the ground cables.

If your application is in a tractor with a 6 volt starter (no solenoid) and coil with a ballast resister, the dummie light will go on the S or center post on key switch, and the coil will go to the I or Ign. Otherwise the motor cuts off when the ignition is returned to the ON position. Great video thanks helped alot

[@dougcrawford6218]

Great job Chris! .. Good overview of the alt, start and key switch hookup .. If the light does not go out and there is and issue with the alternator its usually the rectifier going bad. Normally the alternator is still good and a simple replacement of the rectifier will fix this issue. However, it's still not to say the alternator has an internal short of open winding somewhere still causing the problem. Most people will just replace the alternator costing $$$ where the simple replacement of the rectifier is a whole lot less.

[@williammarvin8365]

You can just replace the voltage regulator which is where number one and number two connect to. It's a chip and it's a lot cheaper. Then buying the whole alternator A lot of times the stator and windings in those GM alternators do not go bad or like you said the diode or rectifier but the diode and the regulator are pretty cheap and relatively easy to replace. There is brushes in there too like an electric motor but they come in a kit I think or you can buy them separate but they're not that expensive. Of course if you're savvy at rebuilding stuff like that, which you are just throwing that at you cuz that's what I do Good video on the wiring I like it!
