Awesome video! I'm fixing to install one of these? So basically is the L pin at alt a 5 volt wire that comes from the ecm....and you basically spliced into that wire so it comes from ecm and lands on new controller, then output from controller to alternator. Then grounded the new controller to wherever the ecm is granded.....and that's pretty much, right? So the 5 volt coming from ecm powers the new controller up?? I would have thought the ecm is constantly changing that 5v signal making it a kind of bad source to power the unit. I'm glad you've already got this thing figured out! lol
Glad the video helped. The wiring diagram at 2:24 shows all of the wires. The quote 'we are standing on the shoulders of giants' applies here. All of this is from researching the work of others. I made this video because I could not find one of an actual install showing the wiring etc. My understanding is, 5 volt power from the pcm is a constant signal voltage for computer signals.
I have a 3.6L VZ Commodore / Holden / GM alloytec like the one in the v6 camaro and Cadillac CTS 3.6L V6 the alternator is a Mitsubishi a003tg1991 alternator it has a 2 pin plug a orange wire and a white wire the pins are FR / F terminal and L Terminal I guess means light ? My alternator isn't charging / exciting I cut the wires off the plug so my duty cycle was 9% when running now it's at 99% when running but it's not charging and dash light is still on so exactly what wire out of the 2 is the one that I need to reconnect keep connected to the alternator with and have it plugged into the voltage reg so it makes the alternator turn on / give it the power to charge the battery orange or white ? I connected it back up the other day I wired the orange wire back into the plug and put it on the bottom pin of the regulator which if you google the alternator the diagram says 2 is top pin and 3 is bottom pin so I had orange wire onto pin number 3 but still no charge it's running off battery power still, duty cycle still at 99% and dash lights still on saying Alternator F terminal Low Voltage ? So have I plugged the wrong wire into the wrong pin or am I missing somthing ?
I drive my car pretty much all day everyday for work, do you think this is safe to put in my car, as far as engine wear because I believe after installing this it causes a constant engine load correct?
The engine wouldn't care about any added load, if there was any. The load should be about the same. The only possible problem I see would be setting it too high, possibly overcharging the battery and shortening its life. Or too low and not charging the battery enough. Adding an accurate digital voltage gauge is my plan. 🤔 I am not an electrical engineer 🤫
@@TSRGarage Right on, I was just thinking that the voltage regulator would cause the alternator to charge at the specific voltage constantly and I was thinking that the alternator on a modern car gets to a certain voltage then stops charging and when it dips down again it charges again so I was just wondering if it would matter to have that constant charge.
@marke.8334 .. I think this system would probably need some constant "babysitting" when you use it. At least until you possibly find the sweet spot that keeps the battery charged enough to start the car. This is the first time I have tried it, and I haven't gotten this on the road yet.

How to develop a system that automatically sets the correct pulse ratio regardless of engine speed to keep charging voltage in 13.7Vdc? Maybe some simple arduino programming? Arduino can be PWM generator that adjust itself to correct voltage or something...
That is "above my pay grade," as they say. I just know this works to get the battery charged. Because this is manually set, it would be possible to overcharge the battery by setting the pwm too high. So, some way to get a state of charge feedback could be helpful.

@@TSRGarage ruclips.net/video/VfbP67zdh9g/видео.html There it is controlled by arduino by a very simple program. But how to keep voltage stable when you rev up engine - have to find out....
New Sub here. I went and got the same PWM that you're using and i ordred 2 myself as i ran into a missing screw issue on one fo them so i could jumo right into the backupo if needed. My set-up is qq little different than yours. I'm trying to gert the alternator in my 06 Dodge Charger to actually charge. I ran into the typical chrslyer relocating the voltafge regulator to the Power Train Control Module(ECM) and the tregulator going on. Well come to find out chrysler no longer supports cars 10 years and older. Which means the computers and or everything i need for it from the dealer has been discontinued. When pricing an aftermarket computer for it i am looking at $550 USED so i went your route with the PWM installation. Problem that i am having is my alternator still isnt charging the battery., it has 2 field wires (i've tried both field wires, and each of the field wires seperately)and the main cable to the trunk of the car where the battery is located. Now i have ran all new cables to each from the what i call bulkhead connection at the firewall to the alternators and the starter hooked the wires up and then hooked up the battery now i had previosuly tried using the linear QS3813 adjustable voltage reulator without sucess so i reused the wiring tht was already in place for the PWM. When you hooked up the field connection to the PWM on your LS swap which field wire did you hook up the the PWM and which one did you leave off or did you use both the field wires in the PWM?
2:24 shows the wiring diagram I used, and links are in the video description. I do not know a lot about alternators. This model of GM alternator originally used a pwm signal to control the charge rate. GM also has alternators that have three wires. On those alternators, a resistor can be put in one of the wires to make it charge.
Was just trying to figure out how to get my alt to charge! Thank you sir!!
hi does to work for single pin alt, there is only one small tiny wire going to my alt regulator its a COM port
I don't know. I haven't used that type alternator
My 2020 Ford Ranger has the same 1 pin voltage regulator plug.

How many Hz(Frequency)from PWM Generated box to alternator
Set to 128.
