Chris, The “SI” series of alternators use a stator connected in a “Y” configuration as all the legs meet. This is the F or field terminal. It is ground when off but B+ when running. If the dash has a charge bulb is a peanut bulb or 194. It is connected to the key-on ignition. Checks the bulb, starts and alternator works, you have 12volts on both sides of this bulb. This light goes out. The regulator controls negative to the rotor, the diode trio supplied 12v to the regulator. The bulb limits current to 0.25 amps or about 460 ohms when on. The “CS is Case Size where SI means System Integrated. The CS uses a stator with a Delta wiring configuration and has up to 32 voltage regulator part numbers. The 4 terminals are marked; S=sense, F=field, L= lamp and P=tach signal or used for remote sensing of battery temp thru a PTC thermistor when the batteries under the rear seat. Any alternator that comes on with one wire at the regulator has a stator that has be magnetized. Like a coil of wire wrapped around a nail, pass amperage or current the nail becomes magnetic even after the battery is disconnected. The nail or stator disconnected from a battery or sitting on the engine in storage over time loses the magnetic field. It has to be jumped quickly to B+ to re-start. If a charge light comes on during bulb-run-check thru the Ignition it has a path to ground either a wire to “L” on the alternator or a gauge or other circuit under the dash. The voltage comparator is a simple cheap circuit device set to 12.8 volts. If voltage goes higher it turns the bulb off by removing ground. It cost about $3 to build. Hope this helps.

I was injured and left the industry 8 years ago. 25 years ago I put a 1 wire on my 55 chevy. A fellow that rebuilds them told me how to do it and wire it in place of my generator. Now years later I am totally building my own wiring system and you gave me some good refresher points as I am planning my install of this one wire again.

This is a quick and clean video with only the necessary information. I like that he is not trying to be a rock star with music and time-wasting fooling around. I wish he were my neighbor. One small observation is that he did a nice job of putting his alternator ground connection on the belt adjusting screw. My new alternator's directions actually pointed out a provided place on the backside to screw in a bolt for mounting my grounding wire directly to the alternator case. It ohms out as a good connection.

Great video mate. At about 7mins down you mentioned someone had the GEN light fitted with the 1-Wire ALT. I do that all the time and never ever had any problems. I use a 1-Wire GM 100A ALT with complete new AAW universal wiring harness for custom jobs. I connect the brown exciter wire to the existing GEN bulb, other option I connect the brown exciter wire to a separate bulb on the dash. It works great and have worked for years. Customers feel safer they actually see the GEN light go off upon starting, like the average car on the street. Just thought I share this info.

Hi Chris, fyi connection 1 is the excite via the "Gen" light, it goes out due to positive power coming back from the alternator when it starts charging, thus positive on both sides, the number 2 is the sensing line, direct to the battery was the original intentions of Remy-Delco, back in the day, auto-electrical technician and engineer 1971-2006, only help out friends in the motor trade now as cars have become computers with wheels! The 2 should be completely separate, bring back the old stuff, and you're right a 1 wire can't have a gen light unless an 11v test module is fitted, somebody fitted it and didn't tell him, stay safe

Just to share, I've been using GM 1-Wire 100A Alternators for all my customers projects using AAW wiring harnesses which already comes with Red/Brown wire connector ready for plugging into these GM 1-wire alt where the Brown wire goes to the GEN light in the dash. So far all the GM 1-wire Alt that I've purchased always had the 2-terminal point to be used if needed. So for those cars without any GEN light on the dash, I'll add on one on the dash panel somewhere.

Hey Chris, this is Dan Baldwin. I had to laugh when I found this. What's funny is my projects seem to be 1-2 videos behind you, seems we are heading down the same path...... Good job first off I'm confused on my situation. Let me sum up 1st. I left something on in my car connected to the cigarette lighter and wanted to take it for a ride the other day and put a slow trickle charge on it the night before. (not sure what the voltage was) the next morning it started with my fingers xed. I started up the rd on a 3 mile trip and noticed a rough engine run like a plug wire off or so. When I got to the gas station and put it in park, the engine cut out. got a jump 2x just to get home. Here is what I checked. Put a volt meter on battery and it was around 11 volts. left the charger on over nite and that got it to almost 12.3 volts. I changed the regulator next day and its the same. it's a 4 pole connector. I thought this was supposed to be around 13.5. any idea where to look. Thanks and keep up the good work. Dan

On a previous video, you showed a heavy gauge wire going to the starter. I did not see any changes to that wire. Should it be upgraded? Also, on my 1972 El Camino, the heavy gauge wire from alternator connects to the battery as in the first video, then to the battery. That is the only positive wire connected to the positive terminal on my battery. I am assuming that the power to the fuse box is coming off of the starter. Does that sound correct? It almost seems like the starter is serving as the junction block. Am I missing something? Should I connect a separate junction block from the starter or the battery? I am hooking to a 300 amp CS-130D in expectation to hook-up a stereo as well as several other electrical devices sometime in the future.

I just put a new 1-wire 100amp alternator in my 67 f100 and it never affected my charging light and no issues. I think the issue is that people delete all the wires from the old harness and just have the positive wire. I ditched all the wires to the external regulator but kept all the wires spliced into my positive wire that were there originally. Edit: Looking at the wiring diagram I wired back in the 904 wire or the Green-Red stripe wire that goes to the charging light.

@davidweston911510 ай бұрын
Great info. FYI the 3/8 size bolt on the junction block is not necessary. You are only using that to clamp the two ring terminals together tightly enough to prevent loosening. A 1/4" stud is better because that means your ring terminals have less material drilled out of them, so they will conduct better than the 3/8" ring terminals and they will probably cost less. You don't need 3/8" bolt, that's big enough to torque to 200ftlbs or more. All you need for an electrical connection is maybe 15ftlbs at most. The only reason to use a 3/8 would be if the terminal block itself is a flimsy design (as it may well be something from china), then putting it a couple sizes larger will compensate for that, assuming they use larger housing etc for the larger stud size.

@fishhuntadventure Жыл бұрын
You should apply any dielectric corrosion inhibitor /after/ you make a good, proper crimp. The idea of crimping is 100% contact, not holding it tight. Dry crimps, whatever dielectric that tickles your fancy (I like the CRC or loctite brands because they don’t dry out and get crumbly quickly) applied afterwards. I prefer crimping and adhesive-filled heat shrink, dry, but like for boats or trailer wiring here in the salt&rust zone a bit of dielectric at the wire to terminal juncture with heat shrink over. Either way, the crimp should be swaged dry.

Question. So I switched over to a 1 wire on my 71 Fastback. So, still having battery drainage and killing my battery. When installed, the OEM wiring harness isn't hooked up to the new alternator but still ties into the volt/reg and into solenoid. I'm thinking the issue is that the alternator isn't being told to turn on to charge the battery? Someone suggested running a "hot" wire switch to the alternator? Wouldnt that be just finding the old wire (prior alternator setup) and running that to the battery?

you don’t use a voltage regulator with a 1 wire get it out of there.. you have a parasitic draw.. running hot wire to alternator doesn’t make any sense... watch Eric the car guys parasitic draw video if disconnecting the regulator don’t fix it.. I had a 67 fast back with a gm alternator before.. threw that Ford shit in the trash

I've installed an HEI to my 67 GTO and it starts fine, runs fine but won't shut off with the key switch. All wires are run through a relay for the HEI. I have traced the wires can't find any ballast resistors and the resistance wire going to the starter has already been done away with. There is a splice from the alternator hot post ( single wire Alternator) going to the starter solenoid main lug. That splice is about 1ft from the alternator on top of the engine going down the front of the engine block to the starter.There is a working voltage regulator on the fire wall. Does that voltage regulator need to be bypassed and would that be the reason the engine won't shut off? The key switch does work properly.

run HEI off IGN circuit 12 gauge wire.. there should be a spade on fuse box

I watched all your videos on alternator upgrades and how to get rid of the external regulator. I did everything in your videos. I have a 69 chevelle and i came across your 100 amp alternator upgrade. I believe my alternator is 115-120 amps. I want to upgrade my charge wire to a thicker wire but looks like my factory 10 gauge wire goes from alternator to wire harness all the way to plug on fire wall. Do i cut that wire and run into juction block witch has fusible link running from battery to juction block to horn relay. Then run a bigger gauge wire from alternator to battery.

@@chriscraft77022 like I said I watched and done everything in the videos but now I need to upgrade my alternator charge wire but it goes from alternator all the way to plug on firewall. Can I just cut the 10 gauge wire out from alternator and wire that into the junction box behind battery then run a 6 or 4 gauge wire from alternator to battery??

Didn't that alternator have the built-in voltage regulator? Are we completely not using that circuit at all on the alternator and the car both?

Hi Chris, I wired my 66 el camino up connecting the wires together - not using the plug and jumpers. My GEN light came on the other day alerting me to a dead alternator. But it ran great with no problems for about 2 years until I put a Holley Sniper EFI on it. Had problems off and on ever since. Now my new alt is showing no charge with my meter on the terminal. Don't know where to start. Ideas? Thank You.

Oh, one more thing - since I put in the EFI the engine continues to run when you turn off the ignition key until you turn off the radio.

What did you do with the 2 extra wires that no longer attach to the alternator?

you cut and cap them off.. or cut them out of the harness .. or just tape them up real good

I'm covering my classic car to a 1 wire 100 amp alternator with a 4 AWG wire. In the video (time 21:23) you mention that the original charging wire was removed completely. Do I cut the 10 AWG wire and removed it ? Thanks Chris
