all my videos are in 1080p.. so check that out
just an idea on how to UPGRADE your charging system to a higher output alternator
car is a 70 chevelle with a 53 amp (already converted) internally regulated 3 wire alternator

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?
What is the point of the junction box? Why not just run the #4 wire directly from your alt. to the battery? Very good video thanks.
Best video on 1 wire so far.
What’s that rope ?
What do I do with the factory alternator wire that runs over to the external regulator when I put in a100 amp alternator one wire? In my 1970 Chevelle?
Nice video.Thank you.
Great video bro this help me alot
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.
Go to Napa auto parts for your turmanals
The generator lights are back fed voltage. Grounded it's a complete circuit. But if voltage is present, there is no flow (ground) so the light goes off
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
Your videos and attention to detail are incredible. I do have a question though. I just installed a 1 wire alternator in a 1969 Mustang and I no longer have any power to the dashboard- headlights, ignition switch, etc. I'm guessing that was a part of the original wiring that was connected to the external regulator that I removed (as per powermaster instructions) Is there something that I'm missing, or was the car not wired correctly to begin with?
Great job. Thanks!
good for u, i learned at AIT electrical engineering school how to rewind alts gen
Great Video
What did you do to the factory charging wire? Did you cap it or reroute it to the junction block?
Grate video I have a 71 Cheyenne Chevy truck has ac planning on putting electric fans and a amp im shure you covered this question but I wanted to ask just to cover bases.so going with a 140 I need to replace junction block and go from junction block to battery and altinator wire to junction block with 4 gage wire my question is the wire going to from existing junction block to new heavy junction block does that need to be 4 gage as well and what about outher factory wires like wires going to sylinoyd on starter or any outher wires can I keep thim factory? Thank you agine for your help.Im also using your videos to fix my 66 elcamino but that comes next .
U forgot to ground the frame
Thank you for your variety of topics. I enjoy your videos. I have watched a couple concerning generator to alternator conversions but can’t quite figure my situation out. I have a 64 Falcon with an external voltage reg that has screw terminals instead of a plug. The guy at NAPA suggested a GM 1 wire alt so that is what I have to work with. Is there a way to wire it or should I try to swap for a different alt?
v nice g m alternator
Another great clip, thanks Chris
When they say "self-excited@1200rpm", I always wonder if they mean crankshaft speed or stator-shaft speed… because if they mean the latter, the drive ratio between the crank & alternator pulleys becomes critical. And if it's less than 2:1, then you can forget having an even an "unloaded" at-idle operating voltage like seen here! [:(
Hi Chris – love your how to videos and the drawings that accompany them . If the answer to what I'm about to ask exists in another of your videos I apologize. I have a 69 Chevelle with the factory Tach with the Batt/Fuel/Temp/and Oil gauge in the same gauge. My mechanic upgraded the alternator to 140 amp but kept the external voltage regulator (had to be upgraded as well) .
I just realized they DID NOT change the charging wire to a 4 or 6 gauge wire (this is so basic they must be clueless) So my question is , if we change the charging wire to a larger one, does it only go to the distribution block by the battery, or does it also have to come off the distribution block and run over to the drivers side of the car to the bus bar / voltage regulator? And do you have a clue what their thinking was in going with the externally regulated VS the internally regulated? Thanks so much.
Plug the blue wire into position one on alternator You will end up with two wires at alternator.
that battery is not going anywhere.. hahaha, the handle is tied between the battery and the block.
I learned A ton from your videos, Probably saved me a fortune on my 67 Firebird alternator upgrade I am currently working on. One thing I don't understand is why do you need to jump the wires on the external regulator plug? Aren't the Blue and white wires that went back to the alternator now dead ended? Why jump them to anything now that they no longer are hooked to anything?
Great Video… I just watched this and I'm subscribing because I can understand exactly what your doing Chris, subscribing as well. I've got a BBC in a '69 Camaro and I'm in the middle of fabbing a dual fan setup, that's going in with a Vintage Air setup and a Serpentine belt setup. Gonna start roughing out some parts list since I'm confined to the house I may as well watch your various Relay videos and more, then start ordering some parts.
