How to run a DR44G alternator without a GM ECU for cheap.

In this video I am showing how to run a 2 pin GM alternator DR44G and control it using PWM and a DC-DC converter as a stand along unit.

Dude, I'm so glad you did this video and so glad I found you.

I just followed your connection instructions and bam it’s working just like yours is. Late model alternator on a 454 running Holley efi!!! Thank you so much I’m sure this will fix many other problems I’ve had!

I just finished this up and it works perfectly. 14.6 volts now.🤘🏼

Following up. I was reading about these alternators and it seems that the they default to about 13.7 vdc anyway... so even if some of these support components failed the alternator would at least still function. I found that good to know.

Yesssuh! I get it and like 10 bucks for the part. I just really thought there was a way to make it work but there's not unless you wanna go through all the changing of the regulator and soldering and crap and basically ending up with the same alternator you just took off. Kinda defeats the purpose doesn't it? Least now you can control the power when adding accessories and that's the point being a higher amp alternator especially running more than one battery. So yes I will be the PART of ebay to runs this awesome alternator. Thank you for confirming this as I had my doubts.

You could assign a PWM output from the terminator X to the alternator. You then set up a graph on the output Voltage vs pwm output. Use the Terminator X for a voltage regulator. Set up battery voltage as an input and PWM to the alt as an output.

I wish I had you here to help with my alternator generators.
I've got CS high output alternators and have the two wire pigtail, but I'm still having problems,
The light wire has a resistor in it then goes to an idiot light then on to a illuminated toggle switch.
Sound right?

Thanks for posting this, I am in the middle of sorting mine out as well. The Terminator has alternator control in the ECU config under basic I/O tab.. Select custom and you can configure PWM table for voltage over duty cycle. I gives a PWM- output only on output B10. I am using a 5v cigarette USB charger as the source voltage and a resistor between the Holley and 5v source wire.. What voltage reading are you getting on your control wire at the alternator 2 pin plug when its charging around 14.3v?

[RecklessRegal]

I have read that the range on these is 10-90% but I've also read that it's 5-95%. Can you test the voltage output at 94-95%? Is that in the diag range or does it go above 15.5v

[roymoore]

so I have an 03 yukon xl that has the volts ranging between 14v & 8v & it gets so bad that it will want to stall out at lower rpms... Can i run this conversion & it will bypass the whole PCM charge thingy you explained? I cant believe this aint ran off a fuse so it just blows the fuse if need be. I do not have 100% understand of it, but I want to bypass the PCM... it doesnt seem like rocket science & is the route/conversion I need to do?

Think you could do a video on a GM CS AD244 alternator?

[silvernblackattach]

Many thanks. So- a DC TO DC Converter and the Signal Generator? Do you have part number for the DC-DC converter?

[silvernblackattach]

Thanks. Another questrion: What 12 vdc source do you use? A "switched source' (via key), or constant 12 vdc from a battery source?

I have an aftermarket HO 250 amp alternator. Uses the factory 2 pin GM plug. 2006 Silverado 5.3L.
Since I have the factory 2 pin plug, what do you suggest to use for a plug that won’t cause the battery light to illuminate on my dash?

[koltonroy]

i gave this a try and it worked for a few minutes but stopped working. Any suggestions?

[koltonroy]

why did you need the 12v to 5v converter?

[niuvarduque]

I tried what you did but on Honda accord 1998 with a 4 pin alternator and it didn’t work. Do I have to leave the computer wires connected to the alternator 4 pin connector or do I disconnect the computer wires from the 4 pin alternator connector?

Rozumiem, że fabryczna wtyczka była 4-pinowa i podłączona była tylko 1-pinowa. Opis fabryczny to "P L IF S" i używany jest tylko kod PIN o nazwie "IF". Dobrze rozumiem?
